    Aggravating gasket

    A lot of you will know this gasket at first sight I bet. Yamaha 2 stroke 40-50hp. Aggervating thing. Seems whenever I get a motor where someone cleaned the carbs, if it's this gasket it wasn't put in right and got pinched and out of place. Now I know you can hold a gasket in place using a...

    Pitting/corrosion on jon boat bottom

    Just my opinion, but once the boat is clean just use it. I don't think your doing yourself any favors with all that sanding ect.

    Replacing water pump seals 50HP TLRB

    Oh, and I have a complaint. Why do they call it a water pump housing when part #21 is the real water pump housing. They should call it driveshaft seal housing or upper seals housing or something appropriate. I'm going to file a complaint, a Formal complaint. Let's see, what did I do with the...

    Replacing water pump seals 50HP TLRB

    Thanks 99, that's what I was afraid of, I already bought the seals and O ring thinking that housing could be re-used. Oh well, live and learn. I was just getting ready to post asking if the seals go into that housing and you answered my question.

    Replacing water pump seals 50HP TLRB

    Haven't done this model and under the water pump and above the seals is this plastic/rubbery part. How do I get it out without buggering it up and if I do does it matter?

    Pitting/corrosion on jon boat bottom

    Get everything out of the boat that could cause corrosion from acid or dissimilar metals. Give the boat a good wash with water and dish soap. Lightly brush if you want but don't worry about getting the corrosion off as it can actually make a protective barrier against further corrosion. Once...

    Cooling Water Path through 2 Stroke Yamaha Outboard

    I didn't think to see how much water was coming out of the lower unit before I started this repair. Knowing what I know now, I see your point. What I had was a strong flow out the tell tail that turned to boiling hot water. That made me look to the T-stat which, upon inspection, could in no way...

    Cooling Water Path through 2 Stroke Yamaha Outboard

    That's along the lines of what I want to do, only I want to go back and forth both ways maybe even getting a shop-vac in on the action. Afterwards, I thought I'd put the lower unit back on and run the motor in a tub of vinegar and detergent for a while before repeating the process. I just want...

    Cooling Water Path through 2 Stroke Yamaha Outboard

    Also, before I do any damage, I want to flush water through the motor to check for obstruction. Starting at the T-stat opening (with the lower unit off) I want to shoot water and/or air in both sides. Then backwards through the exhaust where the tell tale exits and up through the water tube...

    Cooling Water Path through 2 Stroke Yamaha Outboard

    Thanks Bosco, that 2 stroke diagram looks just like my 50HP. In my case it sure looks like a very cruddy Thermostat making problems but I want to flush water back and forth through the passages while I have the lower unit and thermostat out and that diagram and flow chart is just what I needed.

    Cooling Water Path through 2 Stroke Yamaha Outboard

    Trying to educate myself tonight to solve overheating issues on several motors. I'm looking for the path cooling water takes through a Yamaha "2 Stroke" , such as - Pickup - Water pump -Thermostat - Exhaust - Cylinders - Exhaust - Prop Not sure if I have that in the right order. Also, as far...

    Electric Boats

    Thanks Bob but there's no free energy. If the boat is moving under it's own power then the power the generators produce would be less than the power that the drag they produce consumes. Solar power is far, far more efficient than wind or hydro (at least for this purpose) and here in the Florida...

    Electric Boats

    Very true WaterRat, as much as people complain about high electric bills, electricity is if fact produced far more efficiently than other sources of energy (except maybe nuclear)

    Electric Boats

    Well, I see you guys have been talking amongst yourselves while I tended to other matters and I think that's great. Now I'm back. Sold my houseboat, sold my RIB tender and sold the Sundance Skiff project and now with room in the yard I'm back to the electric boat project. I did get the motor out...

    1970 River Queen Houseboat new owner here!

    Congrats Beth. I just sold my houseboat and understand your enthusiasm. If I could give you some advice. You said your first order of business was to put gas in it. One thing you should be aware of is that vapors from fuel can build up inside a boat and if not vented properly cause an explosion...

    Electric Boats

    No, I have not. Having built my own wind turbine from scratch years ago I know that the physics of wind power do not go well with a project of this sort. The amount of energy a wind turbine can produce is a mathematical formula based on the area of the circle defined by the rotor, and for a...
