    adding access hatches to Islander (tracking down a leak)

    oh man, that's the fear! Or, more likely, somehow tracking down this leak somehow turns into a new engine or something... hmm... I've always wanted an outboard starcraft.....

    adding access hatches to Islander (tracking down a leak)

    Yeah, sorry! It's an I/O. I gave a better description of where I think I see water coming in above, but it's an I/O. I would say that this is not a minor leak. I get a pretty solid, pretty consistent dribble of water. Just based on rough calculations with seeing how much water drains out of...

    adding access hatches to Islander (tracking down a leak)

    Thanks. The one thing I know (I mean... "know" is strong because there have been plenty of times with this boat that I've "known" something 100% and had strong evidence and been totally wrong, ha!) is that it's not the keel. I have the leak narrowed down to somewhere fore of the doghouse...

    adding access hatches to Islander (tracking down a leak)

    Hi all, So. I have a leak in my Islander (late 60s), and I can't tell where it's coming from. I have inspected every single rivet on the bottom of this boat and none of them "appear" to be loose or anything, and I've tried everything I can think of to track it down. It appears that I should...

    Trying to reprop, but how can I tell if my engine gets to WOT?

    Thank you all for the replies so far. It turns out that my throttle is only opening part way. I adjusted the cable today and got it working much better. I can still adjust it quite a bit, and it still needs a bit of work, but it was clear to me that adjusting the throttle will do quite a bit...

    Trying to reprop, but how can I tell if my engine gets to WOT?

    Old drive was pretty messed up. Bellows attachments points were corroded away to nothing, threads were stripped, etc. It just seemed easier to replace the whole drive with something in better condition. This took the boat out of the water for months (not weeks and not years). thanks

    Trying to reprop, but how can I tell if my engine gets to WOT?

    Hm.... probably more likely that I messed up the throttle. The outdrive very clearly says "120-140 HP" on it, so I feel pretty confident about the ratio. I'm guessing my throttle is just messed up. I'll confirm tomorrow whether or not I'm hitting even close to WOT. thanks

    Trying to reprop, but how can I tell if my engine gets to WOT?

    Thank you. Sorry, when you say "throttle linkage," do you mean something part of the shifter adjustment (that's in the transom), or part of the throttle lever (at the helm) or part of the carb? thanks

    Trying to reprop, but how can I tell if my engine gets to WOT?

    Hi all, I have an old pre-alpha (MC-1) drive coupled with a GM 165hp inline 6 motor. A few months back, I replaced my outdrive with a different MC-1 drive, but instead of the 165hp drive, it was the drive for the 120-140hp motor. Asked around here and the consensus was, no big deal, but the...

    Mercruiser - GM Inline 6 (165hp) starter?

    yeah that makes sense. I'll probably need to keep closing it up because it does rain occasionally and it's in dry storage like an hour from my house so I can't always just run down to button it up if it starts raining. But I agree that getting the water out might help. Any tips on getting...

    Mercruiser - GM Inline 6 (165hp) starter?

    I should say... I've been saying "rusted" but I guess I'm not sure if rust is the culprit. It doesn't look particularly rusted, although the terminals definitely rusted quite a bit on all of them, so I assume that when they freeze up and stop working, there's rust at play. But the weather is...

    Mercruiser - GM Inline 6 (165hp) starter?

    Hi all, I mean, there's a little water in the bilge, but nowhere near the starter. I have maybe 1/2" of water at the very bottom of my bilge, and then the starter sits up probably a foot or so above that. But this is, like I said, my 4th starter in just a few years. They just freeze up so that...

    Mercruiser - GM Inline 6 (165hp) starter?

    Hello, I have an old mercruiser with a late 60's GM inline 6 (165 HP) engine. I've been through 4 starters in the last 5 years or so, just because they rust and freeze up. I think I'm buying marine starters, I keep buying this one...

    Want to verify that I have the right prop (Mercruiser MC-1)

    @Bondo thank you, very helpful. Definitely expands my options! Appreciate the info

    Want to verify that I have the right prop (Mercruiser MC-1)

    One last question here: I am looking for a new prop, but I can't find one specifically for an MC-1. I see that there are Alpha One props that have the same number of splines, will an Alpha One prop work? Are there any other models with props that will be compatible? Thanks

    ok, will do. Thank you all

    Want to verify that I have the right prop (Mercruiser MC-1)

    Just a thought—if there's a formula about what pitch does to RPMs, is there also a similar formula about diameter? My current prop is a 17p but is 15" diameter, how would that stack up against a 21p but a 14" diameter? The consensus is that when going to this new lower unit, I will probably...

    Removing very, very, very stuck propeller (Mercruiser MC-1)

    Ha, thanks! I guess I can take the time to confirm—on these old MC-1 drives, I took off the propshaft nut, and the little spined washer thing that holds the nut, but that's it—there's another flanged nut thing that the spined washer fits into, and I didn't take that out, but that's fine, right...

    Removing very, very, very stuck propeller (Mercruiser MC-1)

    @racerone That's the solution I see a lot, but in my case, I'm trying to get the prop of in once piece. This is just an extra lower unit (that I'm also trying to keep in one piece), I'm hoping to use the prop on my actual boat! Thanks

    Removing very, very, very stuck propeller (Mercruiser MC-1)

    Hi all, I'm swapping out propellers and mine is stuck. Very stuck. I bet it's had 30 years of saltwater corrosion built up and I can't get it to budge. I've searched this forum and other forums and tried basically every trick to get it to pop, but nothing doing. Hoping that by creating my own...
