    Overrated Horsepower?

    Does it really matter what number they put on any motor? We have no way to verify how much power its really making. Its not as if we can take our boats or outboards down to some dyno and have them tested. At best all we can go on is the displacement, number and size of the carburetors and...

    ID odd length Lower unit 9.9/15hp series

    Could these shafts be out of a different model? The longest shaft I see listed is 32 3/8" for a 25" motor. The shift rod is the same as a 20" (I do have a bag of short shift rods so that part is covered.) I don't have enough short drive shafts. Has anyone cut and made a longer shaft shorter? I...

    ID odd length Lower unit 9.9/15hp series

    I pulled the drive shaft out of the one. It measures 42 5/8" overall The oil in the lower units is brigt blue and super thick. I thought it was grease at first but its the consistency of thick glue. Its spot clean though. The lower housing is completely normal other than the shaft. The shift...

    ID odd length Lower unit 9.9/15hp series

    Only the driveshaft is longer, the shifter rod is the same as a 20" motor and the gear case housing is normal. I have a few Sail master and Yachtwin motors here an they have a long spacer but they're not nearly as long as these things. I've been all through the 74-92 parts listings and can't...

    ID odd length Lower unit 9.9/15hp series

    A local junk guy who prowls the streets here on trash night brought me five OMC '74-92 style 9.9/15hp lower units. He was asking $5 each and they look new. They shift and feel fine, but two are painted a bright green, the green like Johnson used in the mid 1950's but these are 70's or 80's style...

    100+ outboards

    This is why there's no way I'd sell a whole motor or any thing that subjective on eBay. Parts are another story and although its not a set it stone rule, if your ad lists USED, AS IS No Returns For Parts or Repair only and your not a problem seller eBay will generally side with the seller...

    100+ outboards

    The four stroke motors didn't get any attention either, not even those that were like new. Every motor that I put fuel to so far has fired right up but there are no fuel tanks to sell. I have one fuel tank here and its out of my boat. There were a few old pressure tanks, two looked brand new...

    100+ outboards

    Its been 2 years since all of the above occurred and I wanted to come back here with some sort of update. After two seasons listed on CL very few of the lot of motors have found homes. Basically only those with issues sold. CL and FB produced zero sales, all of those that sold were sold by word...

    30 and 35hp power head interchangeability

    The cast prop is black, it could be teflon I suppose. Its a lot heavier than a Solas ss prop that I have for my boat, its at least as much heavier than the bright ss prop as the ss prop is over a stock aluminum prop. I have two Snap On compression gauges, one is specifically for small engines...

    30 and 35hp power head interchangeability

    I have the motor completely torn down now, only the two rods and pistons remain in the power head, and about 5 water jacket bolts and one coil bolt that broke off at the top remain. One piston is about 1/2" down, the other is just above the ports. The bottoms of the cylinders are lightly rusted...

    30 and 35hp power head interchangeability

    A neighbor of mine passed away and they put all his boat stuff out of the trash this morning. I just spent an hour dragging it down the street. He was an avid fisherman but I guess his kids aren't. They sold the boat because it had a title, but gave me the trailer, 15 motors, and a half dozen...

    1979 40hp lower unit stuck

    I pretty much run and prop these to run around 5800 RPM max, so the carb won't be a big issue if I do use that carb. I ended up burchering the mid and power head to get the driveshaft free. I cut the mid in two places, removing a chunk from the middle with a circular saw, that went quick. I...

    1996 Mercury 115 steering cable stuck

    I have a flywheel lifting tool/puller, I had it hanging from the top to mount it up on the stand its on now. The cable end was broke off flush on the starboard side, and not much more than the bolt hole was showing on the other side. That end started to mushroom so I cut it off, and drilled...

    1996 Mercury 115 steering cable stuck

    I picked up a clean looking aluminum Starcraft yesterday. I wasn't looking but it was cheap. Get it out of my driveway cheap. Its a pretty clean boat with no salt issues, but its also got WV paperwork, which will mean a trip to the main DMV office and a month wait for the title but for now, I...

    1979 40hp lower unit stuck

    I've got an '88 35hp here right now that I picked up for parts to fix another one with a busted up skeg and anticav plate. I've had it soaking for a year and its not budged. The power head won't turn and when I flipped the motor over on the bench it sounded like a box of rocks. One spark plug is...

    1988 35hp - Multiple issues

    I've been using a 50/50 mix of acetone and ATF, along with some Aerokroil and PB Blaster. I smashed and peeled that brass washer out it let a spring come up, which I pulled out of the way, as well as an a splined rubber seal or o ring. The pocket around the splines holds fluid for about 30...

    1988 35hp - Multiple issues

    It appears to be a brass washer fitted over the splines that's spring loaded. I can push it down about 1/4" or so and it pops right back up undamaged.

    1988 35hp - Multiple issues

    Its been soaking for over a week, I've tried heat, impact, and all sorts of penetrating fluids but no change. I've cut away about 1/3 of the mid housing to get at the upper shaft as well. Its looking like the only way to separate the shaft from the crank is going to be to cut it out of the...

    1988 35hp - Multiple issues

    Its been soaking for two weeks, I've tried wedges, heat, and every type of penetrating oil I could find but no change. I've cut away about 1/3 of the mid housing and can get a pretty good look at the shaft and exposed splines. If I soak the area with oil, it slowly soaks in and goes down but...
