Good points about the warm, damp bilge/engine compartment!

My friend that bought the Moesly 21 "Unohu" I/O new in 1965 and ran it for 27 years, literally wearing out 3 different engines and drives, was fanatical about keeping the bilge dry! He wasn't satisfied with the main bilge pump because it always left a little water in the bilge. His concern was that windage off the flywheel would spray any bilge water all over the engine so he installed a second tiny pump with a manual switch. Claimed it left the bilge just barely damp! I followed him all over the Bahamas on a half dozen trips, and I noticed that EVERY TIME he put the boat up on plane, being a very methodical engineer, he would turn on that pump and look back over the side to see if it spit out any water!

Ideally you'd like to have a solenoid that is 100% airtight, but if it's the type that's integral with the starter that mechanically actuates the Bendix gear like a Chrysler or some GM types, it definitely won't be airtight, even if ignition protected! And although a wiper-type contact is a good idea, I've never seen a starter solenoid made like that.

Regarding sprays, how do you like Boeshield? I like the idea of the waxy protective coating it leaves, although I don't know how good it is at displacing existing moisture.

nope ! don't like boeshield - I use what I recommend

in my sea craft - I slid a whale submersible pump way back under the motor - they're great - low profile and they'll fit under the motor.this keeps water out of the bilge...

[pelican]

this is the whale pump - highly recommend these !

I've used these a lot on customer's boats - they're easy to mount - they swing around for mounting and the water outlet - fully automatic too

covered rack storage - bad environment ! corrosion city !!


enclosed motor area - like an I/O set up - gets pretty hot in there huh ?

get what i'm saying ?

All good points...normally when I am done boating for the day the boat gets a good rinse,motor flushed and the bilge drained...then i try to leave the cover open until the motor cools down. Now I will have to add the spray to my list

Ter #1, Señor Pelicano is right. Hold out and get the Lear Research "Corrosion Block" - it is the best. It is a little hard to find but worth the search. It comes in a cool rustproof aluminum can, like a little fire extinguisher. The problem is it only costs $4.00 less than the fire extinguisher, but it's still worth it.

Use either "Corrosion Block", "Corrosion X" or "Fluid Film". But for 1st use, use them AFTER you use an electrical contact cleaner.
