I had one motor that was struggling to stay at same RPM level as other, when I started messing with it, I found salt in basically all of my plug wires on that motor, with one wire especially bad. (I was surprised as the wires were new last October) After I cleaned them out it was much better, but anybody know how to help prevent this?
Goup up the connectors with dielectric grease. Don’t be scared to really put it to it.
as far as I know at least…

WD-40, works as well.
Silicone spray
Excuses? I’ve heard them all!
dielectric grease can cause issues with preventing electrical connections
not to be sarcastic, but instead of keeping the salt out of the plug wires, lets try and keep the salt out of the cowling.
whats different between the 2 engines?
I have seen the rubber bellows that connects the block to the cowling, get a pin hole, and spray a mist of water at higher RPMS, over the back of the motor

Heard WD-40 is not a good idea to spray on motors.
Buddy had a 2006 150 Yammy that cracked the throttle housing. Mechanic said it was from WD-40.

Like Chris V said, I have also had a ‘hidden’ leak before under the cowling that happened to be the connection for the peeeee-hole and was spraying some water up onto the plug area causing similar issues.
I have issue with spraying plastic with any petroleum distillate base spray. Use silicone spray for spraying the powerhead down.
Chris V make a good point about dielectric grease preventing electrical contact. If you use it, only smear a little on the inside edge of the boot. Don’t stick the nozzle in the boot and fill it up. Same goes with other electrical connectors like ECM plugs. I have seen several ECM related issues where it was too much grease inhibiting good electrical contact.

This is why I’m confused on how it actually happened.
Nothing different between the 2 motors (except one had no salt present) but there was no sign of any salt water inside the cowlin or on the motor anywhere…
I’ve never even taking the cowling off while she’s in the water.
