Hi All,
Haven't posted for a while so here goes.
Yesterday I had the Columbia 30 (1972) pulled out for a quick powerwash and underbody inspection. On the way to the lift following a good warm up and the ability to get over red line RPM's on the tach. (momentarily) I put the beast into forward gear and immediately noticed that I was not developing full rpm on the motor when in gear.
I thought that perhaps a good cleaning must be needed and this was confirmed by the amount of caked on sludge on the hull and the amount of barnacles removed from the shaft and prop.
The lift operator also noticed after cleaning it all off that I have about 1/8 inch of longitudinal play in the prop shaft when it is pushed in and out towards the v-drive and engine direction. Is this a big issue and how do I go about adjusting this. Walter v-drive installed.
Anyways, this issue with the drive in gear, did not disappear after the cleaning, and even on the way back to my slip, it felt like driving a car with one foot on the gas, and the other foot partly retarding everything by pressing on the brakes at the same time.
When in neutral you can easily turn the prop and shaft by hand with no feeling of retardation, so where is my issue? Could it be that an adjustment of the v-drive is required (slippage?) This did happen one time last summer, but when I did a test run with my mechanic minutes later the problem was gone. now it has come back. The engine is behaving itself and is running within oil pressure and temperature specs.
Help appreciated !
