Several threads in the past on mounts, but not specific to this which I'm receiving conflicting information both from otherwise reliable sources.
When installing engine
mounts one source advises the height adjusting bolts must be parallel to the drive shaft/engine (assuming engine
and drive shaft are on the same plane) and perpendicular to the base of the mounts. Another says the adjusting bolts should be verticle, still perpendicular to the base of the isolation mounts which would be horizontal and the engine feet parallel to the base of the mounts (in this the feet rotate on the engine brackets/bolts to allow the engine to slope to the angle required to align with the shaft). The latter allows the engine weight to load straight down (perpendicular) while the first has the engine load tilting slightly aft, the amount equal to the angle the shaft leaves the boat.
Which is proper and/or how much of an angle/tilt can the isolation mounts accept?
I am replacing mine and note the engine bed/logitudinal stringers tilt aft slightly less than 4 degrees and the shaft exits at roughly 6 degrees. The current
forward mounts have the engine feet set higher on the adjusting bolts than the aft mount height bolts to adjust for this difference.
