    100+ outboards

    He said he's only asking $550 as it is? A good viable 74 to 92 9.9hp should bring upwards of $1,000. The sum of its parts is higher than what he's asking and its probably the most desireable portable motor ever made. Between those and the 9.9hp 2001 to 2006 Mercury four strokes they likely...

    Estate sale lot of 18 - 25hp motors - Compression gauge variables.

    The head has to come off, the piston skirts won't even go down that far, If I could drop it all out the bottom, I'd have smashed the head off the thing from below. The bad part is the thing ran, I just wanted to see why its got such high compression. If they had epoxied the head on all the...

    Estate sale lot of 18 - 25hp motors - Compression gauge variables.

    Day two, lots of heat, large pry bars, pb blaster, and the head won't budge? Am I missing something here? I've applied enough force under the tabs of the head to break it in two but it won't budge. If its glued on somehow, its likely not coming off anytime soon by the looks of things After...

    Estate sale lot of 18 - 25hp motors - Compression gauge variables.

    I tried to pull the head off the one with the crazy compression but it won't budge. I see 10 head bolts, and I removed 10 head bolts, and it won't budge, I've tapped, pounded, and twisted at it and it don't move. Not even a little. Am I missing something here? I was going to swap the head off...

    Estate sale lot of 18 - 25hp motors - Compression gauge variables.

    New taxes on what? We're talking $50 for the contents of a two car garage with a dozen motors and a crap load of tools and fishing tackle. I paid less than $4 in sales tax. Plus I bought those who helped move it all pizza, about $75 back at my place, and a $27 30 pack of beer. Any one piece...

    Estate sale lot of 18 - 25hp motors - Compression gauge variables.

    I started going through them all one at a time checking compression, they range from 96 to 105 psi with the Gale and the '58 FD 12 both having the lowest at 95/96 and 94/95 on both cylinders. The one that's different is the 1968 Evinrude 18, which is about impossible to pull, it gave me 199/200...

    Estate sale lot of 18 - 25hp motors - Compression gauge variables.

    I went to an estate sale with no intention of buying anything in particular but ended up leaving with a truck load of older motors. All but a couple are 18hp models, 1958 through 1975 models. After no one bothered to walk out in the garage in the cold, some old woman and myself were the only...

    Deep Cycle Battery not good for starting??

    Batteries here are shipped to the retailer or shop full and ready to go. Most are sealed with no means to get into them at all these days. The caps are glued down on many, others have one time type clips that break if tampered with. If an outboard is having trouble starting off of a healthy...

    1983 35hp siezed after sitting for 5 years.

    I had an '86 30hp that was locked up when I found it. I took it apart thinking it was either cooked or rusted up from sitting for years but found the inside to be clean. I ended up tearing the power head down and pressing the pistons out on my shop press. I thought I was loosing my mind when...

    1979 40hp lower unit stuck

    I tore apart what was left of the 40hp's lower unit from the boat, since the lower housing was pretty much gone getting the shaft and gear out were pretty easy. I have a pinion gear, shaft, a spacer, a stack of shims, and a tapered seat bearing at the top. The seal and retainer is the lower...

    1979 40hp lower unit stuck

    That sort of makes sense but isn't that lower bearing shimmed? How does this work on the older motor that has no pin and no cavity or clearance for one? On the parts motor, the area beyond the splines in the crankshaft is open roughly an inch beyond the splines. the cavity nearly goes clean...

    1979 40hp lower unit stuck

    My guess is that the thing was likely a tight fit from the start, then a bearing meltdown heated things up and maybe even sort of shrunk fit the iron over the steel shaft. The shaft is hard, a hacksaw doesn't even scratch it. Its also only 40hp so its not likely to matter much. If 10,000 psi...

    1979 40hp lower unit stuck

    Success! After an hour of carving with a cut off wheel the crank end is free of the driveshaft. I had to cut it in pieces and then chisel each piece off the shaft. It was basically welded to it. I was expecting it to be badly rusted but the shaft is super clean. The inside splines are rough...

    1979 40hp lower unit stuck

    Was it all two cylinders or just this model in a particular period? My uncle had a Mercury 400, 40hp that he ran for years, I think that one was a '71 model. My cousin still runs that motor yet today. It looks like basically the same motor as this one minus the decals and oil injection, which...

    1979 40hp lower unit stuck

    I have that puller, but this motor doesn't have those threads. Its an iron hub with 8 bolts holding the flywheel to it with a thicker steel plate and starter cup on each side of the sheet metal top of the flywheel. The outer cast iron ring and gear are riveted to it. The other motor has a solid...
