    18HP Tohatsu - what compression is "good"

    I am going to go look at an 18HP 2005 Tohatsu for sale. What range of compression readings should I expect to see on a good Tohatsu four stroke 18HP engine? My big concern is avoiding an engine that has overheated. The water around here is extremely shallow with coarse sand known for its...

    What is the difference between a 15HP and 20HP tohatsu?

    I can't find anything different between these two engines other than the carberator. The manifolds, ignition, block, head, and crank are the exact same part #. Even the factory prop is the same. It looks like Tohatsu puts a smaller carb on a 20HP and sells it for $500 less. You can buy the...

    Briggs & Stratton - noise & vibration update

    I can't find the original thread where exhaust noise was discussed at length. I finally got around to extending the exhaust and putting the 5HP Briggs on my squareback canoe. It works great. After extending the exhaust about 4" under the water the engine noise is about the same as any small...

    How do I get bow rail fittings off?

    A porpoise jumped from port to starboard in front of my bayliner CC trophy and got whacked really hard by the anchor pulpit. Bent the anchor and split all the hull fittings (CPZ) for the bow rail. Poor fish. I know he's 600 lbs of muscle but that still had to hurt. The fittings are held in...
