leonaj99ParticipantRick good luck in your repower and in making the tough decisions. I just want to emphasize Tony’s comments regarding sub system upgrades/improvements.
Having done a single engine repower myself in the past and having done most of it myself I found an awful lot to do as soon as the old engine was out.
Old thru hulls? Now I have good access so time to install new ones.
Old water system plumbing? Gone and a new system installed with proper angles so it drains for winterizing.
Didn’t like the battery placement so I glassed in new shelves and relocated (battery cable is expensive LOL).
Time for modern raw water strainer and let’s relocate so it’s easy to service.
Now that I have block heaters let’s install a nice electrical outlet with it’s own breaker that’s convenient.
Oh yes, new exhaust hose and custom riser/elbow.Those are only a few on the list but you get the idea.

leonaj99ParticipantI never keep an old used impeller for a spare. I keep a new one for a spare then after 2 seasons I use the “spare” as a replacement and buy a new one for a spare.
I figure that if I have to go thru the work of replacing an impeller especially if under duress, I want to put in a new part.
I’ve done this for 25 plus New England boating years and have never had an impeller failure.1 user thanked author for this post.

leonaj99ParticipantATF has anti foaming qualities which may be necessary. In a BW velvet drive if the engine rpm is less than 2600 it is OK to use motor oil in lieu of ATF. Don’t know what the requirement is in a ZF gear.
I can say from my bearing engineering experience that motor oil is a better lubricant than ATF. -
