Any help is appreciated ...

    1989 Starcraft Islander 221 (4.3 Liter) doghouse rebuild.

    I have just about finished the complete overhaul of my Islander , but I have no idea about fixing the doghouse. Does anybody have some pointers to rebuild that doghouse? If possible with measurements and/or pictures. As always, thank you very much for your opinions and advice. Cornelis

    Charging problem

    you do not mention the RPM you are running it on now, but a rectifier on a 2 cylinder 48 horse will give a good charge from 1800 rpm on. 14 volt is really good for a rectifier.

    Evinrude 25 - Part Missing

    On the top of the johnson evinrude forum there is a sticky that has boating salvage yards. Try and call some of them. They have a lot of good stuff. It is not just the plastic housing. It should come with a couple of bolts and (very important) a round foam like washer that helps it fit onto the...

    Evinrude 25 - Part Missing

    The silencer is important. Maybe not so much for the engine performance, but having it makes conversation on the boat a lot more pleasant

    Johnson 1980 9.9 lower unit leaking oil out of small hole

    The oil you see is most probably a mix of exhaust and water. The hole you see is made in there to drain the gunk that tends to build up in the exhaust housing specially when the engine runs at a low rpm. Just to make sure, do the smell test. Open your lower unit gear drain just enough to drain...

    does anyone know?

    What you see there is a petcock. It is a drain plug that is in there so you can drain the manifold for winterizing. I would take it out all the way and take a piece of bend wire to make sure there is no muck above it . It either was not tightly closed or the rust and muck sort of plugged it up...

    Evinrude 9.9 Overheating

    The compression seems to be low. quite possibly the overheating did a job on the block or the head. 200 degrees is quite hot. My guess is that it will need a rebuild.

    Evinrude 9.5 vs 8hp speed test

    I do not know the exact year, but up to a certain date OMC measured the Horse power rating at the engine drive. Then they started measuring at the propeller shaft and the horse power measured there was always less. For example, the 2 cylinder 35 horse became a 33 horse. In 1985 power was already...

    www.electricaltechnology.org/2020/07/marine-boat-cable-wire-color-codes.html Here are the wiring codes. Trim feed is always independent from the other gauges. Speed often is fed by a pressure setup on the back of your boat. .The faster you go the higher the water pressure pushing into a little...

    Tachometer reading up too 1100rpm once engine rpms is increased tach runs back down to below 0..

    Just for the heck of it. On the back of your tach (dependent on the year) you may have adjustments. It often looks like a flathead screw with numbers around it. If you have a 2 cylinder engine it should be on 2 if it is a 3 cylinder it should be a 3. And so on. You may want to check if it is...

    55 or 56

    I had a few 1957 35 horse engines in that color and a 1958 in the same pattern but slightly different color patterns. The color name is holiday bronze.They all had pin needle bearings and could already be run on 1:50. (I never did). The one thing most people ignore when writing about oil mixes...

    Tachometer reading up too 1100rpm once engine rpms is increased tach runs back down to below 0..

    If everything on your motor runs as it should, your problem is with the tachometer itself. The volt meter going up to 18 volts, points to a defective rectifier.
