Re: Mercruiser III / Group III

well that makes sense as the billed it as "inboard shifting with an i/o drive"

any experience with the reliabilaty of these 40 year old drives? Also what prop does this thing use? It is a 20" vented hub.... same as bravo?

I recently discovered my 1971 Boatel houseboat (47') did not. Have TR Drives but in fact has twin 1965,era Merc Group III sterndrives. I have to replace the port drive and you can probably imagine parts seem to be non-existent. Yes, they are quite big. Does anyone out there have any suggestions?

You may try contacting these people. SPEEDMASTERS I know yours is a little different I would think some of the parts are the same and they know the old stuff.
