    Water Pocket Cover Gasket leak MCM 140 upper

    Hi there. I have a slight leak in the water pocket cover gasket. I thought I'd check to see if the Water Pocket Cover was leaking. The cover does not look melted in any way. I followed the instructions that achris mentioned in a previous post "Remove the drive and separate the 2 halves. Rig up...

    Hi there, I have a 1980 Sylvan (StarCraft wannabee:)) 18ft. SS open bow 140hp Mercruiser IO, I think it weighs between 1800 and 2000 pounds (not sure). This is new to me and I only had a chance to make two 25 mile runs before freeze up. I will just use it for cruising but I would prefer speed...

    identifying plastic ring in front of prop 150 4stroke

    I was seeing if one of my old aluminum props could be used as a spare on a friends 2012 Mercury 150hp 4-stroke. It has a plastic ring that has 3 tabs and fits into the bearing carrier nut and seems to fill in the gap at the front of the prop. My spare aluminum prop seems to rub a bit too much on...

    #1 upper with Alpha lower waterpump question

    Hi there. I have a 1980 #1 Drive serial 565xxx. I split the upper from the lower to change the water pump and it didn't make any sense to me. I think that the upper is a #1 drive and the lower must be an Alpha. The upper has the 565xxx serial number on it and the lifting ring on the top cover...

    1980 Sylvan 18' Sportster Kicker Question

    You guys were so friendly I thought I'd ask my first question. I boat in some very remote areas and will definitely need a kicker. I thought I would look over the winter for a good deal on a 6hp. Trouble is I don't know if I need a long or short shaft. Here's a couple of pictures of my transom...

    Sylvan 1980 18' Sportster IO

    Hi there. I picked up a Sylvan 1980 18' Sportster IO in October and was hoping I could hang out in the StarCraft forum and get some advice on a bunch of work I will have to do? The Sylvan forum is a bit slow. There hasn't been any new posts there since October. I've already seen some great...

    Is ice in the bellows bad?

    I'm guessing it is;). Went down to -8C or 17F last night for about 10 hours. My block and manifold were drained so they're ok. And there's no water in the lower end. Was putting the boat into storage so pulled the drive and found a bit of ice. Will be replacing the bellows and gimble bearing...

    Takes a long time for oil to drain back to oil pan 140hp

    Just picked up a 1980 Sylvan 18' aluminum with a mercuiser 140hp serial 566xxxx. Last week I changed the oil and filter (short filter) and put in 3.8 liters (approx 4 us quarts). I checked it after 5 minutes and it was low. I checked it an hour later and it was at the full mark. Today I ran it...

    Mercruiser 140 Exhaust Riser Drain Plug

    Hi there. Just picked up a new to me 1980 Sylvan with a Mercruiser 140 in it. It's starting to get cold here at night so I'll be draining it after every use. The Exhaust Riser drain plug is missing and replaced with a bolt. The manifold plug and block petcock are fine though. I don't want to...

    NGK YR5 or BR6FS for 140hp 1980

    Just picked up a 1980 Sylvan with a 140hp mercruiser serial no. 566xxxx. I thought the plugs for it were BR6FS but the NGK site lists the YR5 as the plug. Is this correct? If so, what is the difference? I've sent an email to NGK but haven't heard back. thanks

    Humminbird 597 CI HD DI transducer cable design flaw!

    Re: Humminbird 597 CI HD DI transducer cable design flaw! I didn't make myself very clear. I removed my cables from the quick release mount and just plug them in to the unit. There's someone with the same username as you on the CGNutz forum.

    Where do I add power trim fluid??

    Re: Where do I add power trim fluid?? Here's your modified picture. The red circle is the vent. The screw should be open slightly. The green circle is the fill. Fill to that level. If what's in there now looks like motor oil put 10W-30 oil there. If it's red put Dexron auto trans fluid. ps...

    Does 40hp 4stroke EFI have a rev limiter

    Hi there. A neighbor with a Merc 40hp 4 stroke EFI is having trouble getting his boat to plane. It takes too long. We're going to try different props. He doesn't have a tach and I don't want to over rev it. Does this motor have a rev limiter. I'm assuming it should as it's EFI but don't want...

    01 Johnson 25hp mystery connector

    Hi there. Just had a new head gasket installed in a friend's 2001 25hp. I noticed that there is a connector hanging behind the CDI module that I don't think was just hanging there before. Should this connector be attached more securely somewhere. Also what is the connector for - I know it...
