Mercruiser Part Numbers HELP?
 

I am an hour from my boat, and have a crazy few weeks ahead, I am hoping someone might know part numbers or some other way to identify and locate some random parts. Thanks In advance. :drink: Ok, The boat is a 1983 Excalibur Marine 40' hawk, original twin mercruiser 370 454 7.4L v-8. I just had the long blocks done and reassembled both, I need part numbers or help locating OIL PUMP GASKETS, ALTERNATORS, WATERPUMPS, and possibly MANIFOLDS. thanks
Kevin

Thanks for the site, extremely helpful, I am guessing the link for the 330 GM 454 v-8 1982-1987 would be the best pick? mine is a mercruiser 370 454 1983.

look under 370 trs would be yours 1978-1985 according to my mercruiser epc

heres the link for the 370: http://www.mercruiserparts.com/selec...doc_nbr=+86187

Re: Mercruiser Part Numbers HELP?
 

The internals/heads on the 330 will be different from your 370. But from your list, the only thing that might be different is the intake manifold gasket.

Thank you guys. I can finally get the parts I need with out all the guess work and trial and error I had gone through in the past. ( Bringing an oil pump around with me from shop to shop to match the gaskets was getting old) If I can ever return the favor to any of you please do not hesitate.
thanks,

Ok, one more issue, I found the Mercruiser part number 817119A4 for the 55amp alternator, I am not sure if the 55amp or 39amp alt. is used on my boat. I currently want to replace the Motorola 8RG2018 alternator that is in it. Will the mercruiser part 817119A4 work?

Re: Mercruiser Part Numbers HELP?
 

Go figure that the 55amp is cheaper then the 39 amp model!!!! anyway why dont you just have yours rebuilt? Last time i had one done it was a tad over $100 with a 1 year warranty....other then if the brushes go bad for some strange reason it will last you alot longer then 1 year :) It will save you some money work just as good as new and you can still get more stuff

Re: Mercruiser Part Numbers HELP?
 

That is a good idea, and I would at this point do that, except, in my research I found out the non motorola alternator that is currently on my port engine, is automotive, thus not explosion proof, and now I must replace that one.
