Hi people,new guy here with a question. I just accuired a 76 searay srv 200 with a 351 233 merc, got a good deal because there was no stern drive and engine was lock up. Fixed the engine problem,also converted the old 2bbl carb and intake to a 4 bbl if that makes a difference, now need to fix the outdrive problem. Was going to use pre alpha, but a friend suggest I simply use a alpha instead. I talked to someone else about this and they said I might run into some problems with the cooling system, that the alpha stern drive and the gimbal housing are different sizes for the water passage. <br /><br />Any info would be help, thanks.
