    Alpha 1 Gasket set - what are the o rings for?

    Looking at the outdrive to bellhousing gasket set for the Alpha 1 Gen 2 outdrive, there is the gasket, large foam rubber o ring for the drive shaft housing, then four other smaller solid rubber o rings. I think the black one is for the water passage but then I have 1 medium sized red o ring and...

    Like the title says really. Ive pulled the Alpha 1 Gen 2 drive off my boat to renew the bellows. Gimbal bearing, ujs are in perfect condition and the alignment is spot on. Ive read a bit on here about greasing the universal joints on the drive shaft and the coupler but I cant find any grease...

    Mercruiser lubricants and sealants.

    Looking at the manual for Mercruiser Alpha outdrives there is mention of various lubricants and sealants. Is it necessary to use so many different ones and are there cheaper alternatives to the Mercruiser parts? For example, Bellows Adhesive 92-86166 - probably best to use the correct stuff...

    Alpha 1 Gen 2 Crunch when going into gear

    When I put my boat into gear there is usually a bit of a clonk / crunch when it goes in, I guess as the propellor is stationary and then suddenly has to start turning at idle speed. As far as I can remember, its always done it but I was just wondering if its normal.

    Alpha 1 Gen 2 Grease points

    I was preparing my boat to go back into the water yesterday and shoved some grease into all three grease points on the outdrive. Grease went into the 2 points where the drive tilts no problem and began oozing out thus indicating that the joints were full of fresh grease but I pumped loads into...

    Merc 3.0l fuel filter bowl.

    The small fuel filter bowl on my 3.0l Mercruiser is rusty inside. It once had a coating (paint) but this has flaked off meaning that the fuel filter bowl is just bare metal inside which is rusting as theres always traces of water in the fuel. I asked at a Merc dealer and the bowl isnt available...

    Renewing Anti Foul to prevent osmosis

    Hi, I have a 2000 Bayliner 175 which spends 7 months of the year in a freshwater lake and the other 5 months on blocks. I read recently that one of the best defences against osmosis in the fibreglass hull was to strip the antifoul right back to the gelcoat then renew the antifoul. Is this...

    Filling Oil Alpha 1 Gen 2

    Having replaced the water pump in the outdrive I see the manual call s for filling the drive with oil from the bottom up. Is it OK just to pour it in the top instead and wait for it to find its way into the lower drive and for the air to come out?

    Mercruiser 3.0 harmonic balancer

    Hi I have obtained a puller to remove the harmonic balancer from the front of the crankshaft of my 2001 year Mercruised 3.0l engine. The bolts supplied with the puller are metric and so dont fit the threaded holes in the harmonic balancer which I assume are an inch based thread (AF, BSF or...
