    Gellcoat over old paint

    I've been spending a lot of time fixing up an early 1960's 14' runabout and the 1963 40HP Johnson that came with it. I'm learning as I go. The transom is ready to pour Seacast and I'm about to start fiberglass repairs. The iBoats forums are a huge resource! On to my question:<br />The boat is...

    Horribly carboned exhaust

    I haven't seen this mentioned on the board as a possible reason for poor running older motors. I recently redid a 1961 18HP that I got cheap. In the process I removed the exhaust cover and the whole exhaust was completely full of carbon. Not just coated, but actually packed full of black carbon...

    Finding correct gearcase seal kit

    I have spent two hours trying to figure out what gearcase seal kit to order for my 1963 Johnson 40HP RK-25D. That's the Electramatic model. I found the seal kits on iBoats, looks like Sierra is what's offered, and that's fine. But which one? Please help by telling me what part number to...

    Should plugs get wet?

    1961 18HP Seahorse. I got it as a basket case so I've never seen it run. Tore it all apart (didn't open the case though), cleaned every last part, all new gaskets. 95 lbs compression top & bottom. New coils, condensers, points, plugs - excellent blue spark over 3/8 gap. Cleaned carb and new...

    News flash!

    Bondo is a poor choice for repairing holes in fiberglass hulls! I'm working on the transom on my mystery 1960ish 14' runabout (see "Where are the stringers?"). Someone in the past must have hit/been hit in the upper starbord rear corner where the transom meets the side. Punched an egg-sized...

    Where are the "stringers"?

    I bought a 1960's vintage 14' fiberglass open boat, motor, and trailer on eBay cheap. Package deal, local pickup only, and I wanted the 40HP Johnson. Maybe the trailer. Figured I'd just sawzall the boat and haul it to the dump in chunks. I get the thing home and it looks pretty good. First...

    1963 40HP Super Seahorse convert to short shaft

    Just got the thing home; bought it last week (close to home).<br /><br /> http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1,1&item=4534090985&sspagename=STRK%3AMEWN%3AIT <br /><br />I haven't dug into the motor yet, but the flywheel turns by hand and I can feel compression build and...

    honing the cylinder

    There's a terrific thread out there already called "honing the cylinder". Great stuff.<br /><br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=28;t=028330#000000 <br /><br />I understand that glazed cylinders will cause lost performance due to lack of oil seal between the...

    Mystery Fragment

    I've got a 1961 Johnson 18HP FD15 broken down to the major components, am getting things clean and assessing what I'm dealing with. I bought the motor for parts and have never seen it run. It is (was) filthy. But it has 95 lbs compression top and bottom and I'd like to bring it back to life...

    Part#?

    Can anyone provide the part number for the driveshaft of a shortshaft 1969 Evinrude 25HP? I believe the model is 25902. Need to do a compatability check before I buy the shaft. Looks like most 22cube 18-20-25 driveshafts have been superceded with Bomby's part #325800, which obviously makes...

    18HP Driveshaft Length

    I'm converting a 1961 Johnson FD15 18HP from long shaft to short shaft - basically just getting rid of the extension kit. The motor came with two beat up longshaft lowers, which I will turn into one good shortshaft lower. I can cut down the water tube easy enough, but I'm looking to get a good...

    Johnson FD15 and FD21 differences

    I'm looking at a 1961 18HP FD15 Johnson as a potential parts motor for my 1967 20HP FD21. I figure they are pretty much interchangable, same series and block etc. Are the lower units interchangable (bolt on)? I understand there was a Johnson engineering change in 1964 (changed oil mix...

    Replacement prop compatability

    I'm looking for a spare prop for my 1967 Johnson 20HP FD-21. The prop on it now is a Michigan PJ16. It works OK but it's a bit battered. I don't know if it's original (did Johnson motors come with Michigan props?). The OMC parts catalog lists 3 available props by part #:<br />381801 9" X 10...

    Head Gasket Sealer

    I've got the head off my 1967 20HP Johnson FD 21R, and will soon be re-installing. Seloc's says,<br />"Place a NEW head gasket in place on the cylinder block. NEVER use automotive type head gasket sealer. The chemicals in the sealer will cause electrolytic action and eat the aluminum faster...

    Flywheel puller

    I'll be pulling the flywheel on my recently acquired 1967 Johnson 20HP FD21R so I can get at the points, condensers etc. The manuals say I can't use the three-arm gear puller I use on B&S small engines - I'll ruin the flywheel. Gotta have a puller that has bolts to thread into tapped holes on...

    Gearcase Seal Kit cry for help

    I've gotten my hands on 1967 20hp FD 21R Johnson that runs strong once it's started but gets water in the gearcase oil. After reading the forums I decided this 35 year old outboard could use a new seal kit, and I'm the man to do the job. I bought a kit and Seloc manual from iboats and an old...

    Eska 7.0 horsepower

    I've been given an Eska 7.0 HP motor that looks to be in good shape. It has not been run for 5-10 years. No manual. It's a single cylinder Tecumseh engine mounted on what looks like an Evinrude shaft. No reverse. No tilt-lock. It has a built-in fuel tank (with old gas in it), an external...
