    Old motors; Elevated RPM ranges

    I have read numerous times in this forum about running older motors at higher RPM's due to the inferior gas we now use. I am wondering about one of my particular engines, a 1958 Johnson 'fat fifty' V4 50HP. The transom plate lists 4000 - 5000 RPM as acceptable range, and 4500 at peak HP. This...

    Identify part on older steering linkage

    Hello, I would like to know what the circled part is called and where I might be able to purchase one. It is a late 50's Johnson motor that has been adapted to a teleflex style cable with rack and pinion. I think I have seen this referred to as a 'heim' ?? Any help will be much appriciated !!

    Pumping out in floor gas tank ??

    I would like to put a couple of gallons of gas or solvent into the tank of my boat, drive around to slosh it, and then pump it out fully to sort of flush the tank. I have seen reference to an automotive type fuel pump for this application. I have also seen a pump with long tube designed to fit...

    NEW PROJECT: Ever see this type of boat?

    Here is another freebee. Registration says 1984 15' Olympian boat. Came with 1958 Johnson V4 50HP outboard, and the frame and rollers from the old trailer. In one of the photos you see an old Johnson trailer (from another freebee that hit the dump) that I am going to transfer the rollers over...

    Pics of outboard on jackplate?

    I was hoping for some help: I am putting a 1976 merc 150 on a bayliner 17'. Well I want to use this manual jackplate so I can fine tune the motor height. Since it is also about a 6" setback, so the steering cable angles too much and won't hook up. I'd like to see some pics of other setups...

    Seal up transom, mount outboard/jack plate

    I just got a new project; a 1989 Bayliner Capri 17' with no motor. The guy I bought it from had tried 2 different motors on it besides the original force 85. He siliconed the top of the transom where the plastic trim had fallen off. Luckily the boat hasn't seen much water, so the transom is...

    Identify this outdrive ??

    I am parting out this boat and could use some help. What is this outdrive model called? How can I test the trim/tilt function? The engine is an 88HP V-4 2-stroke outboard powerhead - factory configuration. Thanks for any insight.

    Outboard powerhead in I/O

    This is a late 60's 88HP Johnson V-4 in a factory configured I/O setup. I am parting this boat out and was wondering if it is interchangeable with any outboard powerheads.

    Fiberglass Practice

    I'm building a speaker box out of particle board. I want to encapsulate it in fiberglass and paint it - for practice sort of. I would like to use polyester resin and either cloth or mat. I bought some stuff from walmart. Any suggestions?

    1960's Johnson SeaSport I/O

    Is this boat any type of collectors item? I was going to demo it for the trailer. It seems to have a 2-cycle 95 HP V-4 inboard outboard. Weird. <p> Is this an engine worth selling? It does run, I was told. <p> Well if any one has info or experience with this boat or motor, let me know...

    Project started: 1960's FG V-hull

    This was a FREE boat / motor / trailer. I am stripping the boat down to see if I want to use the hull as a base for a budget fishing platform. <p> I will be selling the motor to hopefully fund the project, as it is a nice vintage find. It appears to be a 1956 30HP Johnson Javelin. I think it...

    But Honey . . . . It was FREE !!

    I had an offer of a free boat 2 hours away - thought it would be worth it for the trailer so I got it.<p> I'm going to gut the boat and see what it looks like. I was thinking of either junking the boat, or making a tiller style lake boat out of it. Looks like a similar project to what...

    Help identify material and use

    I have a HUGE roll of what I think is fiberglass mat. I am going to be gutting a boat and doing transom.stringers/floor. Is this something I can use or should use? EDIT: Soliciting not allowed here. <p> <img src="http://www.james.denham.com/Web%20photos/fglass1.jpg"><p> <p> <img...

    Redneck Engineering

    I'm sure many people on here have to deal with removing a motor and storing for awhile, so I thought I'd share. I had two ebay outboards sitting on the patio on pallets. I had been building a motor stand in my mind, but just needed to go buy the lumber. Well we had an old king waterbed to get...
