Bowen Island Paint Job
Hello,
I just bought a rebuilt A4 to replace our rusting 1967 A4. I want to go over her completely, strip and repaint as it has a poor paint job, and add fresh water cooling. The photo below is an old photo of our old A4...very rusty now, but expect I'll be able to rebuild her as well. Want to get her out of the boat so I can rewire and clean up the engine room. Millions of questions! To start with I'm trying to figure out what year our new A4 might be. Has a MM head and MM manifold and was rebuilt in 2009 and then run only 4 hours. Has a sheet metal flywheel cover, oil fill forward, has the little snap open oil fill box just forward of the water pump, has the big Delco distributor with points. I like the cast iron cover so much better, as well as my old style starter. Could I swap over both....maybe need to swap flywheel as well? I'm out of my depth here, don't know if that is possible or a bad idea. I put electronic ignition on my old, small Prestolite dist. Can I swap that over to the new A4 as well and replace the Delco? Any reason not to make these changes (if I can)? Is the bigger style starter better? Lots to sort out! Thanks for any advice, Marty (1967 T 27 Poseidon) |

You've got a real "cobble job". New style head, early gearcase cover, late distributor, early starter and (obviously) early flywheel but with late flywheel housing. Somebody went to work. Oil fill forward suggests late block. Starters and flywheels, early and late, go together. If you don't already have one I suggest you get the Moyer Marine Overhaul and Service Manual available on this site.

I swapped my big Delco distributor out for the smaller Prestolite with EI over a year ago. It works and I have better alternator belt clearance.

Marty, the block date is stamped on the block behind the carb & just under the breather hole & valve cover.
Mine is 041976 - which I am pretty sure indicates April 19, 1976. Ignore the pretty 6 digit embossed number nearby.. I think it is some kind of casting number & is the same on lots of blocks. Here is a dim picture where you can see the casting date just above the flame arrestor.

swaps from 1967 to rebuilt
Thank you for your replies. Just to be clear, the photo on post #1 is of my old (now rusty) 1967 A4.
Good to know I can swap distributor. So, if I want to use my old cast iron flywheel cover I need to also swap: flywheel flywheel housing starter ....is that correct? ...thanks! |

I think bolt pattern is the same for the fly wheel covers. Not sure about starters though, but I suspect they are the same too.
Can you Put the two engines in the same room and check?

Serial numbers
I think it says 052379 on the block, above the carb...does that make any sense?
I removed the blue paint (who would paint that?) from the copper lubrication instruction plate on the transmission. Almost all the info is gone, but at the bottom can still read stamped UJ 74688. Probably an older tranny? -Marty |

flywheel cover + SN
Thanks Jim,
I was posting when your reply came in. Old A4 is on the boat (Vancouver). New A4 is on an engine stand here on Bowen Island.I'll bring home the old flywheel cover later this week and compare. So, Do the two types of starters need different flywheels? So SN = block is May 23 1979? Thanks! |

You can definitely use your old cast iron flywheel housing with the early starter and flywheel. In some cases (mine for example) I use the new (Delco) starter and flywheel with the cast (early) housing. Don Moyer has a discussion of this in The Manual.

Paint thoughts again
Still wondering what the best way to go is. After all this work stripping, cleaning, masking...etc etc..its all for naught if the paint doesn't last. I hope never to see the bottom of the oil pan again, and I want to know its protected.
Today I contacted the major Vancouver marine mechanic service (Stem to Stern), who checked with their wholesaler's paint guy (Western Marine....not West). Came back with the assertion that degreasing, two coats of yellow zinc phosphate primer (95% zinc) and then two coats of acrylic lacquer engine paint was the best way to go. Anyone have any experience with that type of primer on an engine? Any info on how long the Moyer Marine paint lasts? (not that I can get that in Canada) Anyone painted their engine and have it rust free/no peeling 15 years later? Please let me know what you used! Thank you, Marty

Started putting paint to metal...
...and it feels great to begin the next stage. Today I began with the oil pan. It had been caustic tanked last week, came out beautiful, but grew tiny bits of rust as it sat. It took little time to remove that with my angle grinder and a wire brush. Here's what I did after that:
1. I masked all the gasket faces with artists contact paper and tape. 2. sprayed brake cleaner 3. blew dry immediately with compressed air 4. suited up with heavy rubber gloves, coat, respirator, face shield. Garage fan on, windows open. 5. sprayed yellow zinc chromate primer. Had a hard time deciding between that and yellow zinc phosphate primer, but internet search and discussion with a local boat guy who has been accurate in the past decided me. VERY toxic and carcinogenic, but is sometimes called cold galvanizing. He had long lasting good results on two different projects. Can says "industrial use only" so that was a plus. Sprayed three light coats. Used a heat gun in between as it was a little on the cool side. 6. sprayed a medium gray engine enamel: three medium coats, heat gun in between again. Pictures below: #1- stripped (glare makes it look mottled). #2 - masked. #3 - primed. #4 - painted (3/4" oil plug will come out for the Indigo oil filter kit.) #5 - bit of overspray snuck under the masking...it slipped a little when I turned the pan over to spray the top of the flange. More masking later today, spray those parts tomorrow. When my gasket shows up I'll reinstall the pan, flip over the engine and do the same to the block and head. Feel a little unsure about using that primer on the manifold: might use a contrasting colour high heat paint without primer for that. -Marty

Looks great. Nothing like a clean freshly painted engine. So much easier to love.

I have had very good success with electroless nickel (E3) coatings on many components of my motorcycles over the years.
It is an easily applied finish that will cover aluminum or steel parts and offers a very good base for paint of many types. If I ever tear down my 1967 A-4 E3 will be applied to as many components of the engine as I can afford. |

gloating with fingers crossed
Well, getting near the end of painting. Volvo gray and Cat yellow. Should have the new head gaskets and studs before the weekend, and will assemble then. Starter, carb, flywheel housing and cover ready to install.
The end of Phase 1 will be testing. Phase 2 is getting the old A4 out of the boat. Phase 3 is cleaning up the disasterous engine room. Phase 4 is rewiring. Phase 5 is install rebuilt A4! Next winter there may be a Phase 6: rebuilding old A4. Did a partial "dry assembly" of most parts today....an excuse to gloat. Photos below. Every time I go into the garage for anything I end up staying there at least 45 minutes tinkering. Thanks for all the help so far: lots more questions to follow, no doubt! -Marty

I am totally digging that paint scheme! Looks very utilitarian and purposeful.
SCHWEET!!

Hold your applause...
...until she fires up and doesn't leak!
I'm happy with the colours, too. In real life the yellow is a bit more mustard than it looks on my screen (used a flash and didn't do any correcting after). I like the way the light gray makes the parts stand out in contrast. Thanks for the encouragement! The forum really does give me confidence that the inevitable problems will get solved...with help. Hopefully more soon, Marty

studs and head
The long corner stud that goes through the therm housing is the only one I didn't remove. It was very tight, and looks to be JB welded. I figure I'm looking for trouble if I force it out, and have no reason to suspect a problem.
The manual mentions scoring the block deck with an ice pick. I assume that's to help the gasket get a better grip? The engine had hardly been run (by PO) before I removed the gasket, so it cleaned up pretty easily with a razor. Should I do more than that? What should I look for? What about the bottom face of the head (a barely used MMI). I plan to run a tap through the stud holes today to clean rust, etc. The studs that came out had lost a few threads due to corrosion. Any tips about that? I'm not experienced with tap and die work, but gather the secret is go slow, back out frequently, use a light oil. Plan to reinstall with Permatex #2. Hopefully head goes on with 16 new studs on Saturday. I dreamed about top dead center last night! Thanks, Marty

looking ahead
Waiting for my studs and nuts from MM, and thinking about what comes after getting the head back on!
While the A4 is still n the engne stand, I built a wooden skid with wheels, with an extension for the FWC set up. (see photos). Want to test it when I test start. Gauges will be mounted on the top of the plywood. On our Tartan 27 the heat ex and cond. bottle will be in the starboard sail locker....about 2.5 feet aft of the transmission. The engine came with good SW gauges, that were new in 2009. Am I right that G=ground, S=sender, and I=ignition? Wondering what to do for a cheap, easy start switch when I do the testing. Added some photos of my workshop table: ready for assembly! Stil haven't painted the alternator, but plan to. Fun! -Marty

Fun and Exciting for sure!
My critical eye takes over though. There are "two" head gaskets there, right?

For simple bench testing this is what I used. (credit: Neil Dutton)
