    I changed my lower end your oil on my Evinrude 18 hp guy at AutoZone said that should work??? making sure

    Gee, the important debate is not whether this gear oil will work for the OP. I believe that the OP should research/determine the correct gear oil for his motor and not trust random auto parts guys to know the correct answer. Suppose the motor was electro mechanical shift, as lots of...

    Mystery trim/tilt motor

    Looks like an early 80s or late 70s Merc OB PTT motor/reservoir. Not sure if an aftermarket replacement exists, but if it does, ARCO likely made one.

    I changed my lower end your oil on my Evinrude 18 hp guy at AutoZone said that should work??? making sure

    OK, you know that factoid. However, I think it is important for it to be a thought process for the OP, and the lurkers.

    Non conventional issues.

    When you say crack in the intake do you mean a crack in the crankcase cover? It seems unlikely, as crankcases and covers are a single casting and sawed to separate. So what exactly cracked?

    2007 Mercury 115 4 stroke

    I am not real familiar with 4 cycle motors, but I would expect them to share gearcases with 2 cycle OBs. As such, gearcases will normally have a bearing that supports the driveshaft, just under the waterpump, at the top of the gearcase, as well as a bearing where it meets the pinon gear. They...

    I changed my lower end your oil on my Evinrude 18 hp guy at AutoZone said that should work??? making sure

    First of all, is your gearcase mechanical shift or some sort of electromechanical shift, as the older Johnnyrudes were? For mechanical shift motors, I would use a marine gear oil for mechanical shift motors. Most modern marine engine use it. Even Wallyworld usually carries it. If the...

    SS prop for?

    Take a look at the spline length of the prop. Mercruiser and Mercury OB props have full length splines. Johnnyrude props have splines that are about 1/2 as long as the prop hub, starting from the prop nut, forward. Not sure what Yammie has. Luckily, larger OBs and MerCruisers share prop hub...

    Stainless Prop Film

    That is not galvanic corrosion. I ran a SS prop in salt water, and used to get a bit of classic galvanic corrosion where the blades met the hub. I had zinc anodes and an impressed current (MerCathode) system on the boat. It protected the outdrive just fine. However, you might see if it is...

    12' Pontoon/Fishing boat nose diving issues!!!!!

    Is the motor shaft length correct for the boat? Longer shaft motors mounted on shorter shaft transoms, tend to drive the bow down. Trimming should help a bit, but raising the motor up on the transom is a better idea.

    Mercury Flo-Torq II Locking Tab

    Gee, bend down all the tabs that are in the right position. On the six tab washer, usually 3 are bent down. If you pull the prop for the off season, the tab washer will last at least a decade. Will your prop last that long? I have installed new tab washers, over the course of 40 years of...

    RDS-22 1960 40HP Johnson

    Those junction boxes were common on those old motors. You might try a salvage yard and see if you can get one. You could easily make one up. They contained the starter solenoid, a rudimentary fuse box, a voltage regulator for the generator(if you have one), and wiring for the keyswitch...

    Need to fix this hole

    That looks to be well above the waterline. If so, you can just fill it from the outside with kitty hair poly putty, sand it smooth and try to match the metalflake finish. If it was below the waterline or more structural, I would recommend you grind the hole to taper and make it oval, then...

    Wondering why my boat drain plug is at the bottom not on the transom?

    That is a style of drain that was on older (60's) boats. They usually had a clam shell facing stern. If you look at them while on plane, the clamshell holds back the water and the drain is clear. They work as well as transom mounted drain plugs, maybe better. If you can get to it easily, I...

    2006 Evinrude 60 horse etec keeps blowing 10 amp fuse

    First, is the amperage of the fuse correct? I would have expected a 15A fuse. Secondly, the fused power from the ign switch powers the tachometer, trim gauge, fuel gauge, gauge lights, PTT and other etec engine control stuff. I would look for melted wires in the wiring harness, at the motor...

    Vintage 9.5: Can you set points with a timing light?

    Remember, the spark plugs fire just as the points open. You want them to open, just as the timing marks align. Some motors have a "window" in the flywheel, allowing point adjustment with flywheel on. If you do not have such a window, pull the flywheel, set the points with a feeler gauge and...

    Marine Carpet Glue For Wood Decking

    Gee, I live on saltwater and keep my speedboat on a lift. A nice sunshiny day will dry it out real well. I hose it off after use and don't think/worry about wet carpet. I have never had blisters on the decking under the carpet. If you do have an issue with the decking, I would check to make...

    can anyone tell me?

    Very likely that is the overheat switch. it will connect to ground when it detects motor overheat. You will want to connect it to the negative side of a horn or buzzer. Most newer controls have those built in.

    Vintage 9.5: Can you set points with a timing light?

    You can use an ohmmeter to set the points. You want them to open at the same time relatively to each other. I do not know if a timing light would be an improvement, on those magneto systems..

    Marine Carpet Glue For Wood Decking

    Gee, my speedboat is carpeted, is from 1974 (49 years old) and I put a new deck in it, likely about 15 years ago. The old one had multiple screw penetrations from battery hold downs, seats, brackets etc, and only lasted 34 years, before it rotted. Damn that carpet for rotting the deck.....

    Restoring 92 ranger 397v carpet and seats

    Not sure you can get custom carpet or seats, but standard carpet and seats are abundant. You can choose any indoor/outdoor carpet, and mastic. Wise and other brands have a pretty good selection of marine seats.
