Anyone ever change out the transmission on a 37?

Wondering if the engine needs to move or if moving the shaft back 1" or so is enough.

Also, is replacing it any harder than an alternator, fuel filter, fuel pump, wiring harness......

I think the spline engagement is more than one inch....

See page 5 here:

Looks like 54mm, a little over 2 inches.

Also, if you're planning this in-the-water and if you have a dripless seal then moving the shaft back and forth can get a bit wet.. be careful!

Several years back I posted the steps I used to replace the gearbox on my '37. Hopefully this link works:

If the link I posted above for changing out gearbox/transmission does not work, the post was dated 9/30/2009 and titled: "Transmission Noise".

Need a lot more info:what boat? What engine? what year?---

Sorry...too quick to post. Engine is Univ 5432 and trans is Hurth HB-100. Vessel is C37-1981

I too had the Univ.5432 with the Hurst Trans. and I developed a trans fluid leak.Called Univ.engine dealer Helpline (Hansen Marine) was informed that in order to unbolt the trans from the engine the engine must be removed from the boat to access the bolts which are inside the bell-housing.Very poor engineering by Universal.Since my engine was from 1982 with many hours on the clock I decided that if the engine was coming out then that engine was not going back.I pulled the engine& trans and replaced with a new Beta 37.5hp and never regretted that decision.PS I sold the old engine on ebay.

good luck,

Nifty good or4 maybee best solution, a trans is easy to rebuild, just gears washers and shifting forks on pivot pins.

Thanks to all! Nifty...kinda hoping I don't have to replace engine. The 5432 is working fine. The older post indicated the aft end of engine could be lifted 5 inches and the housing removed....hope so! Not sure how to lift the engine. My sole is not the removable kind....yet
