I have a 1981 28 ft Bayliner Victoria Sunbridge with a standard GMC 5.7L carbureted engine with fresh water cooling.
The engine is tired and burns a fair amount of oil.
The engine is flanged up to an AQ280 with a Duoprop
I have the opportunity to pick up a used (300 hr) newer MPI 5.7L
The engine is complete with everything still attached (exhaust manifolds, alternator, electronics, hydraulic pump, etc)
It was originally flanged up to a DP-SM Drive unit
The engine is a 5.7 GI-E
I believe it was pulled out of a 2000
My question is, how difficult would this upgrade be to pull off?
Is it a fairly ease upgrade or is there a lot to it that would need to be changed, if its even possible?
For instance, specifically:
Will my exhaust manifolds from my present engine bolt onto the new engine
Or will the new exhaust manifolds flange up to the exhaust yoke on the 280
Does the new one have electronic throttle control or is it standard cables?
I don't have any use for the hydraulic pump, so what's the best way to deal with this?
Will the motor mounts drop into the same place on my motor blocks?
Electrically is it difficult to hook up?
Would I see much of an advantage with this engine over a rebuild of the present engine in the boat?
I'm looking for any input from anyone who may have gone down this path to steer me clear of it or tell me its a great way to go.
I like the idea of the MPI for ease of starting, but I'm open to suggestions.
Thanks for any insights or suggestions.
