It is not going to just bolt on.
You will need this:
https://moyermarine.com/product/lift...t-ovel_02_221/

And this:
https://moyermarine.com/product/alte...l-ovel_03_222/

And this:
https://moyermarine.com/product/alte...t-ovel_13_558/

Note the generator does not power the water pump, the accessory drive powers the water pump and the generator both.

Just looking over all 3 items........still can't figure out if there is one that will position the alternator over the pulley on accessory drive?? Would it be the new lift eye bracket??
I am ready to get all that but want to be sure . Thank you Joe!

The lifting eye is what lines up the alternator. You can fit a 10si, but make sure it is a MARINE 10si.

thank you Joe,
placed the order with Moyer Marine for all brackets.
Looking for the alternator, NAPA and other automotive part stores want me to tell them what car I need it for
Took generator out of the boat and found some markings...

Well, received Moyers brackets yesterday and my new alternator. Alternator was build for me by Scott from The Rebuilder in Kent WA. He made it to my specifications: Delco style, S10, 63A, single wire, for marine motor...price $85 He will work on my original generator, as I want to keep it in case I would like to go back to original set up.
Spend few hours planning how to fit it into my 1958 Atomic 4. Moyer brackets were useful. The lifting eye needed some modifications, support arm would not fit my motor. Today everything fell into place.
Started the motor and watch the voltage reading in horror....only 12.2V !r
But after 5-10 seconds reading was getting better and better and end up being 14.4V Success!!!
Going to the boat in few hours and will be taking it for a spin and test of new alternator.
Thank you everyone!!

Wojo

The single wire self excite alternators need a bump in RPM to start charging, something like 1000RPM.

FYI - Your 14.4 volts is too high for gel batteries if you even want them. It is a bit high for wet cells too for float, I would be checking the water frequently if you stick with it.
Being a simple powerboat without a lot of hotel loads you may not really care to do any more work on this, but the 10si series of alternators have a lot of regulators available for them. You might hunt around for a lower voltage one if you want to.

Joe,
I am still testing the whole set up, including alternator. Yesterday I was cruising at 1000rpm and was getting charge 13.5V.
Motor was pretty hot......how hot? ....will be checking that today. Stuffing box is not letting one drip of water trough - will be looking into that today too. So lots more to do. BTW, I wouldn't know what to look for as far as regulator - all I know that there is one inside

The 10si series have internal regulators. You can get them in various voltages. They are pretty cheap too, in the $15-$30 range. 13.5 is a tiny bit low, you want to see 13.8 at least, but that may be all you get at 1,000 RPMs. If you get a chance, rev up to 2,000 or so and see if you get more voltage. The only time I am at 1,000 is in a marina, cruise RPMs for me are in the 1800-2300 range.
Re the engine heat, with the thermostat out and the bypass plugged you should be able to run about 120-130 degrees. If you cannot do that, something needs fixing. I had an engine once that needed a vinegar flush every year or it would overheat.

13.2V was at 1000rpm. at 2000 was 14.3V
The motor temperature was high at the head area, around cylinders was OK....here are few pictures and my latest video on new alternator.
https://www.youtube.com/watch?v=h4vRs0bWUX8

Before reassembling the motor I had head checked for cracks and it was fine.
I will be redoing the windows so I can open them. Thinking also about getting an air blower for the motor to keep it cooler. There is plenty of raw water pumped trough the motor, based on how much is coming out of wet exhaust pipe.

Your voltage range sounds fine for wet cells, I would not worry about that
As for the temperature, what does the gauge say? 99% of the time engine temps are discussed, we are talking about the gauge, not IR gun readings. The IR gun will have varying readouts around the engine. Do you not have a temp gauge?
BTW - none of the readings on your IR gun are too hot.

For comparison here is a table of engine temperatures taken with an IR gun during testing of the new MMI thermostat, raw water cooled late model engine.

Joe and Neil,
All I had was oil pressure gauge. Installed RPM guage and hour counter. This motor does not have a thermostat!! Have improved oil pump in it by Moyer Marine - wider gears pumping more oil trough the system.
Thank you very much for your input on alternator charge and table on temperatures in various points of the motor. I am feeling much better about all that. What's left now is keep running the motor for my enjoyment

2 Dogs..great update.. all the detailed information you are getting is awesome. You need a friend to take a few pics of your boat out cruising!!

Back to the technical parts, as regulators go, I have mine (the old 35A Motorola but I found an adjustable regulator) set to pump about 14.2v into my old school flooded wet cell 12v batteries. They might be 10 years old by now...but I also have very small loads..charging my iPad or laptop I use for navigation and some LED lights, and running the anchor wash down and fresh water pump...short and easy loads.

Good luck !

Thank you Shawn!!!
I would LOVE to have a video of my boat under power! Unfortunately don't have friends with boats. Had really nice old tugboat stopped by to tell me that they like my boat, but they didn't want to be boat friends - I am guessing my boat was too small
I have a drone, but I am afraid to fly it over water, I may not be able to land it precise enough.

We need to get Ajax back in here to talk about his drone pics. He takes 'em all the time.

I sent Ajax an email...hopefully he will provide some helpful input! Your selfie stick video was pretty cool, regardless!
