    I was poking about behind the dashboard of my Bayliner 175 (2000 year) today and saw that there was a warning buzzer fitted. Its hanging from a cable tie and is connected with bullet connectors to the wiring loom with a mauve wire and a brown / blue wire. The wires in the loom are the same...

    Throttle cable adjustment?

    Mercruiser 3,0l in Bayliber 175. While observing the gearshift linkages and throttle on the carb, I advance the throttle lever forward (or into reverse, doesnt make any difference) and the first thing that happens is that the boat goes into gear, with no increase in engine rpms. Only then after...

    Drain water after every use?

    Ive got a Bayliner with Merc 3,0l engine and the engine is fitted with the 2 drain hoses to drain the engine block and exhaust manifold into the bilge. The boat is in the (fresh) water 7 months of the year. Should I be draining the water out of the manifold and engine after use to reduce...

    Are my engine Mounts OK?

    I was working on my Mercruiser 3,0l today and discovered that by pulling and pushing (sideways) on the top of the engine, I could rock it maybe 1/2 inch (this with the exhaust system off). Is this acceptable for the engine mounts and what should I look for to see if the mounts are still in good...

    Water Shutter / Flapper Valve?

    Alpha 1 Gen 2 merc 3,0 litre engine. On pulling the exhaust apart I discovered half the flapper valve was missing. Is it worth replacing this part? I heard that Mercruiser themselves had ceased fitting it in new boats.

    Should I invest in a new Exhaust Manifold?

    I pulled the exhaust manifold off my boat today (Merc 3.0l) as the rear end cap looked really badly rusted and I think there has been some water seepage there. Although there was some heavy rust, the underlying metal seems to be sound although I obviously cant see inside the water jacket. One...

    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.

    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.
