Bobtail Engine Replacement Options for Crusader 8.1L Inboard Engines
TOPIC: Available Big Block V8 Replacement Marine Engine Options for Complete Drop In Bobtail Engines
QUESTION: I am interested in purchasing two (2) 8.1L Inboard “Bobtail” engines as direct replacement for some tired 8.1L Crusaders w/ ZF Hurth 63A 2.0 transmissions. My question is what all is included with the “Bobtail pkg? Regards, Patrick
RESPONSE: Big Block V8 repowers have changed significantly within the Marine Industry over the past few years because of the discontinuation of the 454, 502 and 496 engines from General motors. Mercruiser has developed their own 8.2L engine however it comes standard with the catalyst control system which makes it more costly than in years past, and a little more challenging when repowering older applications. The only option with regards to replacing the 385 and 415 Hp big block V8’s is going with a big block 496 CID motor from the Mercruiser CPO product line. The other and more common option for replacing the L29 (330 Hp big block) is the 383 Mag Mpi. I would recommend reading the articles we have regarding repowers and see what option best suits your need.
