Yeah . . . I posted this on there too. 2.4 and 2.5L plates are very different.

so big, before i go to the parts store i want to verify the gaskets i need with u.

for the upper plate i will need #29 and 29A?

and for the exhaust i will need part # 24 and 26 and 33? the guy says he can have the powerhead off in about 30 minutes.. or do u think i can reuse the gaskets that are on there? it has only been run 2 times thanks again

What you've marked is correct . . . I've only ever used one base gasket (29 or 29a) under the powerhead, but go by the book . . . I'm kind of a hack when it comes to this

You might also be able to reuse 24 if it's in good shape.

The guys right . . . he should be able to have that powerhead off and the gaskets changed out in less than an hour. I would supervise if I were you. Make sure he cleans the surfaces well before he puts the new gaskets on given his history of mixing 2.4L and 2.5L adapter plates.

Also I would recommend getting more than one base gaskets (29 and 29a) Just in case you forget to put the shift shaft back and muck up the base gasket (it'll save you a trip to the store).

i really hope this fixes the problem im having. i have 5 mercury dealers in my area so hopefully i can pick up all the gaskets tomorrow.

It will!! You defintely have mis-matched plates on there now . . . It's gonna be a smokin fast lil' boat with that motor ... good on fuel too. Which carbs are you running? Also make sure you yank the spark advance/idle stabilizer module and oil injection if they're still on.

so i get the gaskets and get to the shop and the guy says he will pull the power head but thats it because that exhaust plate off the 2.4 wont fit in that 2.5 leg. if i want to change that exhaust plate i need to pull the whole engine off the boat next week and wait for him to have some free time to do it!? what the hell is this!? so i might be gettin an engine lift tomorrow and tryin to do the whole thing on saturday. can this be done in 1 day??
