boat sunk...why? should i sell?

[captainpond]

I have a beautifull 74 CC that had a 150 hp mer optimax. But it sunk in the slip last month. engine has seized. NO one can tell me why! Not even the owner of the marina. My boat was fine in the water for 4 weeks, and had a brand new bilge and floater put in with two new batteries running off a dual switch. Can anyone help me? I cant believe this.

20 or 23? I assume 20 with the 150

Does it have in floor drains and an in floor livewell?

[captainpond]

yes many foor drains. Live well valve may have been opened from what Ive gathered. Im just trying to make sense of ALL this. 20 foot boat
thanks

Sorry for your loss I know that must really get to you. I couldn’t say why you boat sunk but according to Insurance losses approx 90 % of all boats that sink sink at the dock. Usually the most common reasons are tides which can cause small boats to get wedged under the dock and when the tide comes up get swamped, bilge systems, batteries, hoses, and leaks plus rain.
Personally I keep my boat on a trailer 95% of the time and when it is in the water I will check it or I am using it every day.

You can find a drop on powerhead on scream & Fly for under 2K - good place for whole motors too

don't forget you'll need to deal with all the wiring , lights, etc on the boat too

i called this gentleman and gave him some very usefull advice.truth is when a boat sinks in sea water,there's big problems-the reason most,if not all,are "totaled".as a marine repair service operator,i've seen more than one sunk boat .the engine's first,the fuel injected outboars,and the direct injected outboards are totaled-due to the cost of the electrical components required-fuel injection ECM,,harness's,various other components-the engines won't start and run,the water can't get fully removed from the powerheads-basically,they're junk.gone are the day of flushing carbs and pulling the plugs to blow the water out...throttle and shift cables,these may work now,but,not for long-same deal with the cable steering system.boat-well,if the batteries were"hot",count on there being a considerible amount of stray current electrolysis-look for a white powder on the aluminum-this is aluminum oxide-if it's apparent on railings and other aluminum parts-it's on the fuel tank-see where this is going ? dead batteries,this isn't the case.the electrical system,every wire in the boat will need to be replaced,every electrical component as well-with the exception of bilge pumps...
then,there's the structual end of this...
it's unfortunate when things like this occur.but,dealing with submerged boats,there's more than meets the eye

Pelican, thanks for the call. I am going to sell the boat, unfortunately.
