Unfortunately both links lead to the same info, that for the MC1 to Alpha, ie there is...

    Lesson learned about boats...

    Took my Bayliner 175 out for a run yesterday with a couple of friends. It had been raining all morning but was forecast to clear up in the afternoon so I insisted that the trip was on and that the weather would get better. By the time we got to the boat the rain had stopped and once we got out...

    Bayliner 175 question

    Hi My 2000 model Bayliner 175 has a kind of slot on each side of the inside of the boat where the rear most 2 seats are. The slots are about 3/4inch high and 10 inches long about 4 inches below the sides of the boat and have a plastic surround. What are they for? My best guess was that it was...

    Alpha 1 Gen 2 seals.

    Im trying to decide if my Alpha 1 Gen 2 drive unit is pressure tight or not. Ive made a pressure test rig out of a few bits of pipe, a tyre valve and a plastic threaded fitting but Im not sure if the threaded fitting is sealing against the drive. Bond O kindly advised putting an o ring against...

    Outdrive Pressure Test Questions.

    Ive made up a rig to pressure test my Alpha 1 Gen 2 outdrive (car tyre valve, pressure gauge, tee piece and some piping). The bit that is to screw into the outdrive is an outdrive oil filler nozzle from one of the plastic filling pumps. This has only a plastic thread on it, will it seal or will...

    Used drive oil colour and pressure test.

    Ive drained the Quicksilver high performance gear oil from my Alpha 1 Gen 2 outdrive after maybe 30 hours of use this summer and its a pretty dark opaque colour. Putting a small sample in a glass vial and looking at it it just looks dark and a bit cloudy. If it had water mixed in with it then...

    Impellor change - Merc or GLM?

    Ill probably be changing the impellor this winter in my Alpha 1 Gen 2 drive as the one thats in there will have done 3 seasons. I have a GLM impellor in my cellar but Ive heard that GLM had some bad press in the exhaust manifold and riser dept. Anyone know of any quality issues with GLM...

    Warning buzzer?

    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...

    Exhaust alarm fitting?

    I want to put an exhaust temperature alarm on my boat which has a Mercruiser 3,0l inboard engine. Rather than buy a kit, Ive bought a temperature controlled switch and a buzzer and I need to fix the temp switch to the exhaust downpipe. I was planning to fix the switch to the downpipe (just...

    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...
