Indigo FWC

My boat is laid up getting new rigging. So while I can't sail I replaced the leaky head. When I did that I also opened the clean out and did just that. Some PO had been there before because the cover came off easily. I cleaned the cooling passages up with a mind to finally, finally, finally switch to FWC.

I emailed Tom Stevens (Indigo) and he had a new pump with his kit and was asking $450 for it. That price pushed me over the edge and this afternoon I drove up to Williamsburg and picked it up.

Of course lunch was involved. We had a delicious Brunswick stew, some thing with ham in it and finished with apple pie and coffee. And talked. I love being an old(er) retired guy. Tom is a very nice fellow.

Tomorrow I will start installing and keep this forum informed as to my progress. I have a little over a week before the rigging is done so I figure I have plenty of time- bugs and glitched included. Wish me luck!

One concern expressed on this forum re. electric FWC has been related to pump life and motor voltages.

The new pump that comes with the FWC kit is a brushless motor rated for 10000 hours. The Indigo site says that the "speed of this brushless motor remains constant with an input voltage ranging from 9 to 15VDC. For this reason there is no need to have a Ballast Resistor to manage the voltage level and no concern about overloading the motor with either too high or too low voltage."

I have no affiliation with Indigo.

The short life of the previous electric motors was my excuse for not going to electric FWC. I am now going to wait for the exchange rate to improve...

I tried a cheap supercharger intercooler pump that failed in short order but since installing Johnson CM30P7-1 pumps (two in series) I've enjoyed reliable operation for many years. I'd be interested in hearing any information you may have on the short life mentioned in your post.

I never had any issues with the Johnson pumps either, but I did run them through ballast resistors. Keep in mind with typical useage rates of sailboat engines, a 1,000 hour pump could easily last 10-15 years.

This speaks to the discussions we have had in the past about newer, higher charging voltages and the effect they have on ancillary equipment. The new chemistry batteries might be happier at the expense of connected equipment.

I re-checked the spec sheet for the Johnson pump, 12VDC +/- 20% (9.6 - 14.4VDC). Personally my coolant pumps are in good shape without a supplemental resistor by staying with conventional batteries and 14.2V alternator output.

Quite true. In a normal season on the Chesapeake, I put about 100 hrs on the engine each year (winds become light to non-existant in July-August).

On the other hand, our last trip down the ICW and back saw over 500 hrs on the engine hour meter!

To me the flow rate of the new Bosch pump is a bigger benefit than the lifespan. Up in Canada it is no issue, but here the raw water can be over 80 degrees quite easily, so cooling can be marginal.
