Scenario: 1988 Beneteau
Moorings 432 with a Phasor 49hp engine
likely installed around 2003. The engines were sold with above transmission
. I have had the well known issue of poor shift to forward but no problem in reverse which is said to be due to worn clutch
plates or thrust washer. In any case, I am at the point of rebuild
or replacement. I am writing this post for others as I could not find specific informations related to my boat.
The job: so, finding rebuilt 150s or new ZF 15Ms is not a problem. Alternatively, one can install a Twin Disk which has better reviews
. Removing the existing unit is not easy to say the least. The prop shaft isn't bad. Shift to forward to lock shaft, remove bolt, shift to neutral, rotate shaft by hand to next bolt, repeat. I also left index marks everywhere possible for installing linkages etc. The bell housing or adapter plate has 8 bolts on this setup. They are 14 mm. Use a 1/4 inch drive if possible as there isn't much room for bigger wrenches due to other obstacles or the housing itself. The 2 bolt on the bottom are especially hard to access. Lots of pretzel moves and gymnastics.
I then had to unplug the engine
harness and fuel
return hose. The throttle cable linkage needs to be removed so you can remove the transmission
. Then crawl in the engine space and push the prop shaft back about 2 inches. In theory, the whole trams should slide off the flywheel. NO. Not that easy. tap housing with a hammer and work it loose with a pry bar carefully. Now you can slide the unit back and clear the flywheel/damper plate.
The linkage in my boat required an 8mm socket and 11 mm socket and this may be unique to my situation.
Next step: either remove trans and adapter housing as a unit or remove the four Allen bolts holding the plate youths trans for easy removal
from engine space. This is where I am at now. Hope to update soon
