[QUOTE=onestepcsy37;1402437]i've got a perkins
4-108 with a velvet drive transmission
and 3 bladed prop.
according to the velvet drive manual it's ok for it to spin while under sail. but it is noisy and i've often thought about just clamping a vise grip around the shaft and letting it jam up against the hull
. the reason i haven't done that is because i'm afraid i'll forget to remove it when i need to use the engine
Used a vice grip on our W32. Worked fine. The few times I forgot to take the VG off, it just released on it's own when the engine was put in gear
. A pain to find it under the engine pan later, though. Scoring the shaft would be somewhere in the middle, if it should happen, and shouldn't be a problem as the stuffing box is usually well away from the area that the seal will ride on.
I'd be afraid of using a pipe wrench. Those things generate serious torque and bite harder as more force is applied, should the shaft turn. if the wrench didn't release.
Can't get at the shaft on the current
boat so am practicing my knot
tieing to see if it will work. Doing that had never occurred to me. Mahalo for the tip
says not to lock their transmissions in gear
. The noise
of the spinning prop drives me crazy, though, so I do it. So far the transmission
has survived a TransPac with it locked in reverse.
