repower for 1977 20' CC

[McGillicuddy]

Welcome aboard tj, good to see another SD SeaCraft.

I would look at the Etec 115 or the Suzuki 140. Optimax 115 is same weight 375/390 as Etec and cheaper, albeit louder, but the etec has more cojones. The zuke is about 420 lb with oil.

Between J&M MotorSports, and Pacific Marine Supply, there is enough support for the zuke service, and its gearing will offer much better performance than the 400 lb. 4-S Merc or Yamaha 115s .

Plenty of Merc service options, but not sure who's working on Etecs other than Sunset Marine, in El Cajon. Etec and Optimax, can both be used at Diamond Valley, Tahoe or wherever.
