My plan is to redo all the exterier items on the motor. starter, alternator, ignition, plugs, wires, and rebuid the carb over the winter. But I need to know what I have... Thanks for the help.

Also where can I find the cheapest prices for this stuff...

Be sure you do the electronic distributor...look through Links Section to source all this stuff out...and what does it say on top of that air cleaner?...

that is a 3.7L 165 hp engine. It has the 4" heat exchanger (the good one), and external alternator conversion(some one already did you a favor). The 2bbl Mercarb, and an aluminum manifold with a cast iron riser. first things first, check the gasket between the riser and manifold, it should have one edge of the gasket that goes straight between the mounting bosses, the other side will scallop between the bosses. If it doesn't have the straight edge on one side(indicates what gasket you have) I suggest replacing it with a factory mercruiser gasket. Second thing, do a search for pertronix ignitions, get the conversion kit, you'll thank me and every one else that recommended it later. Set the timing at 4 degrees BTDC. If you can find a large throttle body 2bbl Rochester marine carb off of an 898. 888, 200,230 mercuiser, you will be happy with the swap, if you can find a 4bbl carb/intake/oil cooler setup, you'll be ecstatic. Looks like the charging system has been taken care of. Look around the balancer for signs of anti freeze, there is a weep hle that lets antifreeze out of the cam shaft drive seal starts to leaking, . If it passes snuff, you will have good use out of the motor.

Welcome DD... good looking engine,can't add much to what spare and the guys have already said.
I have an earlier model of same engine, as already mentioned find the weep hole in the water pump housing..it's at about 7'oclock on outer edge facing eng. might want to poke a toothpick or soft wire in it to clear any crud that might have it blocked, run engine and check for leaks.
I used the Pertronix II ignition and Fiamethrower II coil. Up sized plug wires to I believe 8mm for hotter coil and gapped plugs at .040.
These engines had some weak points but with modern upgrades, which you already have most of, are strong running and economical especially if you do your own wrench turning. Any questions just ask and someone here will have an answer...great bunch of folks.

Hi again. YOu talk about a " if you can find a 4bbl carb/intake/oil cooler setup ". Can you be more specific...part numbers...where I can buy...ect...

Thanks for all your help.

Hey Devildog, looks like you got a 3.7 Mercruiser. Check EBAY, I just saw two 4 barrel intakes if you're interested. Look up Mercruiser 3.7 or 170, should give you plenty to check out! Good luck!!

[cfelton]

Oh, I think Mercruiser stopped production of these motors in 1989. You can still find parts, just have to shop around so you dont get ripped off. If you need anything specific just ask. I'm sure we can help you find a good deal on it.
