Was a big block chevy engine optional in a 1986 scarab1 - 21'?

Spec sheet says "Max. Horsepower: 260", then on the options list, it didn't mention engine upgrade, so I'm not sure if someone special ordered it, or swapped in more power. Dan at Archer Marine could probably answer that question off the top of his head!

I don't have an '86 brochure, but if its the same hull as the attached image from 87 or 88, just without the integrated platform.

As far as I know Wellcraft never offered the 21 with a big block.

'85

Short answer is no

Thanks, here is my delema, i recently bought a 1986 scarab 1 with alpha 1 outdrive (inside of boat) with other misc parts, and big block chevy exhaust manifolds with risers and was told the last engine in it was a bbc, however the thru hull exhaust holes in transom are in stock location, i just picked up a 454 short block but wondering if i would be better off installing sbc and selling the bbc parts

Really depends on your budget and goals. If you keep the alpha drive, go with a small block.
get up to ten posts and post some pictures

Ive seen a few of the members scarab1 boats & mods turn out really good, & wondering if anyone has one of these older 21' scarabs with the bbc installed & if it drastically changes the handling characteristics of the boat, also the boat does not have trim tabs, are they a must with a big block?
