Subject: Removing the 4.108 - Rebuild or Replace

Antifreeze leaking into the oil, 3 oil changes, no difference. Engine has been sitting for 15 years without being run, but I got it started with new fuel, filters and oil, started easily, runs smooth, no smoke. However, antifreeze corrodes the bearings and who knows what else. The engine is a mess externally. I've got to remove it and either rebuild, quote locally $8,500. wow, or attempt to rebuild myself, have never done that before, or find a replacement such as a Yanmar 3JH40 for $5,800 new including gear, panel etc or Possibly a 50HP Beta which I hear will line up on the mounts.

Seems I should keep around 40 HP.

I plan to remove accessories and drive to reduce size and wt before I get the engine out. Thinking I may be able by cutting out the bulkhead under the mizzen step to slide it out of the cockpit.

This project can be seen here


Thanks for any advice,

[> Removing 4.108 -- Bruce, - Monday - 09/21/20 - 2:45pm

I took my 4.107 out thru the companionway with a couple of cable winches and a rear "sky hook". I have a write up with pictures that I was going to send in for the projects section. I'll see if I can get that done ASAP.

I ended up replacing it with a rebuilt 4.107 in order to keep the same prop, shaft & transmission. Also installed it thru the companionway.
