Major Motor Problems
 

Well I posted last week about cam sensor , turns out there is major problems:eek: . had Mechanic look at it and it seems starbord motor injested water thru exhaust. I was told that there is a flaw with fountains design with the exhaust being too short. Now engine has 0 compression on cyl 4 an 50 % on cyl 8 anyone hear of this or experience this :readinghelp:

What engines are you running?

Im running 525s staggered

what exhaust and is motor stock?

everythings bone stock boat only has 35 hrs on it

maybe leaking header,,,

dunno. I was told by Mechanic" I did some research and this was a flaw made my fountain." I find it odd only from not seeing anyone else say they had these issues.

I call BS on the mechanic's statement. Did you ask to see his "research?"

In my mind sounds weird. but what do i know :lolhit:

:drink: give the boat to me then you won't have any more problems.:drink:

LOL gee thanks.... guess thats end of this summer:eek:

well bad news there is in fact a issue with exhaust and how fountain shortened it which in turn was the cause of the motor injesting water . SOL:eek:

Wow that sucks :eek: .

your telling me. What confuses me is even if reggie shorten exhaust pipes what affect would that have on water in oil I dont get it. Unless there was a crack or head gasket failure .

It was most likely reversion it is when water from the exhaust is sucked back into the motor. Do a search on here there is alot of info about it especially on the 525 merc.:)

thanks First Afence I looked that up and that is indeed what it is. Dropping it off tom for repair hopefully the summer isn't shot

Glad i was of some help . Hope they get you up and runinng soon::D

Likely has CMI headers? They suck! You can have them tested and welded if they are not too bad. I have them on my Donzi and have replaced 3 so far. Have a motor with only 160lbs comp. on the port bank due to that. Im going to rebuild that one in the winter. Good luck!

Put some rubber FLAPS on the end of the tail pipes. If you have a large wave hit the back of your boat and you don't have rubber flaps that will close on water impact, the water can travel up your pipes and into your cylinders. This can easily happen if your engines are turned off and the water is ruff. Once you have water in your cylinders and you try to start the motors, BOOOM!!:grinser010: I use the clamp ons. It's a cheap investment.
