    Top speed?

    I think Glastron had in it's little Salesman book that the SX175 would do around 42 with the 3 liter. I used to have a couple of copies of those books, but I can't find them.

    1971 Evinrude SkiTwin carb Bowl

    In 71, the 40hp block that Evinrude and Johnson were using, was replaced with the Gale Division 40hp Block. Same Bore and Stroke, but different block. It didn't have the Thermostat controlled Cooling System, or the Midsection that E and J had been using since 1958, and returned to the Midsection...

    Starflite 3 75hp starter issues

    The propshaft is not engaged to either the Forward or Reverse Gear when it is in Neutral, so it can spin freely. Removing the Lower unit from the motor takes the Forward, Reverse Gears, and the Pinion out of the Equation. Once it is off try rotating the Flywheel, if the Motor now turns freely...

    Starflite 3 75hp starter issues

    Without a History on the Motor, anything is possible. If the Engine had been under water, and was running when that happened, Things like Connecting Rods, can and do bend, and will result in an Motor that can stiffen up when rotated. Also Cylinder Walls and Rings could rust, and close up...

    Starflite 3 75hp starter issues

    I was wondering if you were serious about Rodents stockpiling stuff in the Cylinders, as it could interfere with the Pistons from gettin to TDC, If the engine had been stored other than Vertical, and even then, Rodents could have gotten that far in there

    As suggested, drop the lower unit, and see if it still binds up. With the Spark Plugs out, can you see the tops of the Pistons?

    1957 Johnson 35hp overheating

    The Impeller is only one of the Wear Items that make up the Waterpump, the Housing and the Plate below the Impeller are subject to wear too

    boat and trailer sit very low (to my eye)

    You could relocate the Axle to under the Spring, that would increase the Height a bit, or replace the Axle with one that doesn't have the Drop. Added height might result in increased Aggravation at the Boat Ramp though

    boat and trailer sit very low (to my eye)

    Pictures would be Nice. I suspect a lot of people would be happy to have your Trailer, as it makes for easier Launching. I have to lower the Tongue of my trailer as low at it goes, to get enough height at the Back to lower the Outdrive. As for your 250, maybe it, like a lot of Trucks these Days...
