The divider plate gaskets are 18-2502, water jacket covers on head are 18-2808 and head gaskets are 18-6862 which all can be ordered here on iboats.

Common causes for increasing temps/over heating when running at 2500 and above;

Incorrect ignition timing, Verify timing control lever is moving throughout its range, not sticking and causing retarded timing at large throttle opening. Also verify correct WOT timing.

Leaking head gasket(s) mentioned in earlier post.

Powerhead base gasket leaking cooling water into the exhaust, bypassing the cooling system.

My dilema now is I called crowley marine to figure out what model my motor was to order parts and from the only serialnumbee I could found they say it is a 220 xri but it says on covers 200 blackmax and top of enginesays xri so no im not sure what the motor is and what parts to order

Re: 88 mercury black max 200 cylinder wall help

Xri ids a fuel injected motor, if you got carbs it just a 200hp, same parts.

Hey guys I really need your help.got the heads and everything else together. Started the motor today and it runs perfect but water is leaking from the head gaskets I followed the torque specs of 35ft in proper sequence. St first there was a pin hole of water streaming out. I went a round and snugged all the bolts again and it got beter but there still seeping all over. What is going on here? Should I keep tightening and se if it stops I'm already beyond the 35 ft lbs. Thanks

They are silicon impregnated gaskets, they must go thru a heat cycle and be retorqued when hot/warm...

Re: 88 mercury black max 200 cylinder wall help

So its normal for them to leak at first? I kept trying to tighten the head bolts and it seemed to get beter what should I do now?

Should run for a few hours before you retorque head bolts.You are using new gaskets and you have cleaned up mating surfaces?
