    1968 Fastwin 18hp High Speed Needle

    Quick question for you guys: Is the high-speed "needle" (screw at the bottom of the carb) fixed for a 1968 evinrude fastwin? I tried adjusting it and it had no effect on high speed, except coming out and dumping a bunch of gas. It wasn't like the low speed needle; it was just a small screw. The...

    Deck Reinforcement

    Hey guys. I've been given the boat in the below picture from my Grandpa. I've spent the last couple of months (in the Evinrude/Johnson forum) tuning up the engine (1968 Evinrude Fastwin 18hp).

    Sierra 18-7351 Fuel Pump

    Just a quick question. Is it alright to unscrew the filter (little plastic piece on the outside) and turn the hose connection in a different direction? My fuel hose comes in from a different way and I just want it to fit straight in.

    Motor goes WOT when disconnected from fuel tank?

    Re: Motor goes WOT when disconnected from fuel tank? What would be the cause of the fuel pump dumping fuel into the block and how could i diagnose it? I did run the fuel cap completely loose and still same issue. I bought the fuel line from academy sports and it came with one of those quick...

    Motor goes WOT when disconnected from fuel tank?

    I had another thread going, but it became too cluttered and I think it will be best to start a new one. I've been having trouble with my fastwin not going WOT. The boat surges and sputters when I open the throttle, but doesn't have a trouble screaming when in neutral--although it does take a...

I read that the cavitation (or anti-ventilation) plate should be even with the bottom of the transom and mine is about 4 inches below. Here is a picture. What do yall...

    18 hp Fastwin Bogging Down

    Hey guys, new to iboats.com I've done a bunch of searches about this topic, but haven't been able to find anything that will help me. I was just given a late 60's or early 70's Evinrude Fastwin 18hp by my grandfather. The motor hasn't run in probably 5-10 years (but it started right up) and was...
