    Cavitation Burns

    I had the same thing on the TP prop on my speedboat. The metal was actually pitted. Fill the pits with marine putty and prime and paint. Not sure if it is cavitation or ventilation burns.

    What is she?

    Evinrude used to make boats under their own name. That kinda looks like one, with it's rounded features. The had the Evinrude "E" as an emblem, if I remember correctly. Look on the steering wheel for that "E".

    Doghouse reconstruction

    A metal frame is not necessary, and can get heavy real fast. Also, a lot of doghouses have non-90* angles, which will be difficult with angle iron. 1/2" plywood is fine. I recommend you dry some pressure treated CDX for this job. Stick it in the rafters of the garage for a couple of weeks...

    Tilt Fluid

    Dextron ATF is better. In the old days Ford had it's own special formula (Type F), which was not recommended by Mercury Marine. Not sure now. Does the PTT motor run in the up position? If so, help it up by hand and lock it up. Now fill it with ATF, and let it bubble out air a bit. Now...

    Wooden stringers

    Sounds like your Doug Fir was actually pine. A lot depends on where you are in the country/world. I would use dry pressure treated pine for your stringers. Plywood is stronger, however, if it gets wet, it falls apart. The PT stuff will still last a very long time if it gets wet. If you can...

    Winterizing: Fuel in tank options?

    If your stabilized gasoline becomes smelly over the winter, your stabilizer isn't working properly. I do not have any issue with stabilized gasoline staying pretty fresh over the winter. Adding fresh gasoline in the spring is always a good idea. At this point the debate between filling the...

    115 mercury carb problems

    So if your cylinder has no ability to exhaust, it will have no intake either. Relentless bugs....or you have a clean engine. A clean engine is a sign that you do not boat enough.

    2000 Johnson 2cyl 50 missing bolt help!

    For the record, I believe it is for a temp sender. I have something similar on my '98 Johnny. As an easy doublecheck, sender will have NPT tapered threads, and a bolt will have straight threads.

    Setting transom with epoxy

    Epoxy will bond well to polyester, and vice versa, provided the existing glass is sanded and clean. Always wipe existing glass with acetone, prior to adding any resin+glass. Epoxy bonds are stronger. I use epoxy for high-strength repairs. That would be structural repairs like punctures in...

    Setting transom with epoxy

    OK, probably too little too late. General stuff for transom replacement. Replace transom with like materials, say plywood and cloth. Use Polyester resin, as was used in original construction. If you want to tighten clamps, use thin resin, and give it a long time to cure. Put cloth/mat...

    1979 115 hp 6 cyl inline 2 cycle timing/carb adjust

    Most will tell you to toss the idle stabilizer. When you set the timing pointer, you should have set the #1 piston to TDC. Now make sure the dial indicator touches the exhaust deflector on the piston top and zero it. Now back off the flywheel until the dial indicator treads .464 inches. Make...

    Gauges

    Gee, those should be standard gauges and use standard senders. Standard fuel gauges should work just fine. Trim gauge senders are unique to engine manufacturers. You might doublecheck your gauge to see if it matches your sender. PS I always got rid of my trim gauges, in favor of a water...

    Maintenance costs?

    The full list of winterization is a bit longer, but not much more complicated. Stabilize fuel by adding correct amount of stabilizer for fuel in tank, run motor on flusher to get stabilized fuel into engine. Fog engine with fogging oil. Some motors have a setting for this, older motors...

    Combatting Water/Damp Conditions inside of boat?

    Winter weather has low absolute humidity. So if the boat is well ventilated and covered to keep precipitation out, it should dry out and stay dry. Rip out the carpet and install those soft plastic mesh mats. They dry much faster.

    Gee, how did they manage to live in that environment with carbon, exhaust and oil everywhere.

    Gauges

    If the gauges are OEM specific, they may be hard to find. My '88 SeaRay had teleflex gauges, with an SR emblem on them, in a blue green. Luckily the replacement tempo gauges were real similar in color scheme, but without the SR. They were unnoticeable after installation. I guess the word is...

    Shaft extension

    You might look online, as you really need someone who is parting out. I was able to buy a new swivel pin from a shop in Green Bay, Wis, so obscure parts are out there.
