Flooded my seadoo a couple days ago in lake water. Started noticing low RPM's and the throttle would not go. It eventually died on idle.

The water did not go above about 5". Had to recharge the battery but now it seems to be ok. I got all the water out, checked the cylinder for water and nothing. I know the engine doesn't have water in it.

Today I got it started for a few seconds out of water after I gave a slow charge to the battery. It make a LOUD screech when turning over now. I read it could be the bearings on the pump. Anyone have a clue what it may be? Again, I can get it started for a couple seconds then a Very loud screech until it dies a couple seconds later.

Thanks

1. My nephew is an engineering officer on a cruise ship. he says it's a hard and stressful life for an officer, and is a hundred times worse for domestic staff. You are several months at a time away from home (he has 12-week duties), your daily watches are 12 hours long, you have very little contact with the outside world because your wifi and email is extremely limited. You can buy time from other crew members, but the going rate is a month's pay. You are rarely in one place long enough to go ashore. On some cruise lines (but not all) there are significant problems with theft, sexual violence, and people simply disappearing from the ship with no investigation of what happened to them.
2. "how is that job different than others?" which others do you want to compare to?

There are plenty of bot brands that fit your requirements. Sea Ray, Cruisers, and Striper are some brands still in the SF Bay Area up to Sacramento Delta. There used to be more, but sadly, many left due to the high cost of business, and the lack of buyers.

There used to be a similar product for getting recalcitrant petrol engined cars to start on cold and damp mornings .
The fuel/air mix made by the carburetor was condensing onto the interior cylinder walls before the spark could ignite it - so a spray of ether into the carb would create an explosion or two inside the engine and warm things sufficiently for the normal self-sustaining process to work .

We were always warned though that the engine could become somehow " addicted " to that , and would continue not to start even in normal environmental conditions without a " fix " of gas .

I'd guess that has happened in your case .

Simple cheap answer is carry on using a squirt of what it likes to make it go .
Complicated expensive answer is to take it to Rehab ( Marine Engineers ) to sort out the problem .

Yes you can , rip the disintegrating ones out , scrape out any glue / gunge left behind
( raid the wife's cutlery drawer for an old soupspoon and rub a sharp edge on the spoontip to make a suitable in-shoe scraper tool )

A store selling hiking boots should sell you pairs of inner-soles that should make a sturdy replacement , these will need trimming to size ,
( but for God's sake dont be tempted to use her dress-making scissors ! ) .

Depends on what trolling motor and batteries and what speed you are content with.
I have I think a 40lb Minn-Kota that works surprisingly well on a 12ft catamaran (with fairly low drag). They provide a graph of throttle settings against battery life and it's about an hour at top speed ("5"), which is probably a bit less than the speed I could row a rigid dinghy - the cat is too wide to kayak and I don't have sweeps or oarlocks. That's rather less than you'd get with even a small gas engine, but the electric motor is quiet, lightweight, non-polluting and reliable. An 80-lb model would be better, but you're still not going to be wake-boarding.

(incidentally, minn-kota comes in freshwater and marine versions and the freshwater one will rust)
