MILD THUNDER

iTrader: (3)

Since we've had a couple threads going on, about the speedmaster drives, helping educate guys on what they are, what they measure, when they were made, and so forth. I'd like to start a thread though, about personal experiances with them. Like how much power you put to them, with or without failure, what failed, etc. My experiances with these drives are

38 Fountain. SSM #4 small shaft drives. 240 hours on them currently. 175 hours with 650HP engines, last 65 with 800HP engines. No failures.....yet. (my boat).

Friends boats.

1986 38 Flatdeck Cig. 600HP 540's. Standard #3's. I think around 10 seasons on them since rebuilt.

39 Aronow Cat. 625HP engines, standard #3's. Not sure on hours, but been on boat since the late 90's. No breakage.

41 Apache. 750HP 598's. #3A drives. Unsure on hours, but also been on boat a long time. No breakage

1986 38 Flatdeck. Past 4 seasons with 800HP engines and 3A's. Prior to that, 4 or 5 more seasons with 600-650HP engines, no breakage.

All the above boats used on lake michigan, and do see some rough water. Who else wants to share their SSM 3,4,5, experiances?

Ssm 3's on 38 Flatdeck with n/a 800's only failure was due to water intrusion. 8 hours after rebuild fine, same drives swapped on to 40 hawk 5 hours later there still good lol.
Soon to be swapped onto a 40 fountain.

Does anyone have pictures of these drives? I'm not sure what they look like.

I always wondered how much additional power does it take to run 3A's vs. Bravo's and Bmax's? For example, there's a nice looking 1993 42' fountain (except swim platform mod) with stock HP500's and V's got me thinking....what would that run with bravo's vs. these?

abmotorman, if your looking for a Fountain that sure is a nice set up and if it was staggered it would really be the nuts. put some big super charged engines in it down the road "so to speak" like it used to have.

That is a sweet boat. I'd rather have it with 5's than bravos. Lotta room to upgrade power with 0 drive worries.
