I am looking at purchasing my first scarab. It is a 1977 30' S-type. It is currently equiped with 2 350's and 2 trs outdrives. Has anyone ever converted this size of a boat over to a single engine. Something like a 502. If so what are you seeing for speeds?

On a side note what does a 30' with 2 350's see for speeds?

I had one that did 70,the motors were a little rubbed though.Do you have any pics

I think that if you convert it to a songle engine boat it will be real slow unless you put a LOT of HP in it. And then it will just break drives.

These motors are also rubbed. Estimated horsepower is 320ea. The boat also has TRS drives which I hear are better then a bravo!

Here is a pic!

I have a buddy who has one, he's seeing low 70's with twin 502's and bravo's, very heavy. Good rough water boat though.
