    Alpha 1 gear oil in Bilge

    Hi guys, I have a 1987 3.0 Merc, alpha 1 drive and have recently been getting gear oil in the bilge. I have read some previous post on this and it would seem the u-joint seal is gone. I did recently have the drive off to replace water line 0-ring. I put the complete gasket kit in and placed the...

    Marine vs Auto belts

    Hi guys, I know marine belts are recommended over auto belts due to lower risk of spark but it seems like highway robbery that the merc belt is $35 and the same belt at napa is $5. I know, burning the boat for the sake of 30 bucks isn't worth it but just wondering if anyone really thinks there...

    '87 3.0l Harmonic balancer

    Hi, my crankshaft pulley let go on the weekend and I had to get towed back to shore. The rubber grommet between the pulley and the outer ring disintegrated and the manual states it cannot be re-fastened, obviously because it would no longer be balanced correctly. I'm trying to find a part # but...

    RPM vs Pitch-any equation?

    Hi, I have a 20' Imperial with a 1987 3.0l Alpha one drive which currently has a 15x21 aluminum prop. The best WOT RPM I have hit is 3100rpm. The engine, ignition, and drive are all recently tuned and are finally working great. Is there an equation to determine the pitch to acquire the 4600rpm I...

    Alpha one lower shift cable

    Hi, I know there have been many posts on this issue and I've read them all before removing my Alpha one to change the cable. Unit is a 1987 Alpha one coupled to a 3.0l Merc of the same year. I was having trouble shifting which kept getting worse over time. Reverse was worse than forward, so I...

    Distibutor Lubrication

    Hi, I was wondering your thoughts on lubricating the distributor. Not the lower shaft and gear, but the centrifugal advance weights and springs. I have been having alot of squeaking from mine since cleaning it up. Prior to this, there was a bit of oil in there and it was heating up and...

    How long is too long on WOT?

    Hi, I have a 1987 3.0l merc with i don't know how many hours on it. Compression is good (138-142) timing set 6 BTDC, dwell at 31, new plugs, wires, cap, oil, filters, new fuel, new coil, carb rebuilt, the list goes on. It starts up well, and takes off well in the water-aside from a hesitation at...

    Heat tube on a 2bbl Mercarb?

    Hi, I recently rebuilt my 2bbl Mercarb with great success. Engine running much better now. My question is, the Seloc manual I have speaks of a heat tube on the choke housing and I have also seen it mentioned here in the forum but I do not see a tube of any sort other than the clear tube from the...

    '87 3.0l backfire/stall/stumble

    Hi, I've got an '87 3.0l mercruiser with Alpha one drive. Engine runs extremely well on muffs but in the water (salt..haven't tried fresh) it idles rough, will stall on acceleration, backfire through carb BAD, and most times won't take any throttle at all. Once in a while it will take off and be...

    Anyone ever hear of Imperial Boats?

    Hi, new to boating and got to say this site is great! I just bought a 1987 Imperial VC200 with a merc 3.0l alpha one. The only way I knew it was a VC200 is you can see the faint outline on the transom where the labels used to be. My question is: whatever happened to Imperial? I can't find any...
