Re: starcraft chieftain? what should I look for before I buy
in fairness, you're talking two different leagues $wise.
donorboat with good V8 I/o drivetrain can be had for <$1000 if you're not in a hurry, or willing to drive to get it.
a bracket will be more than that alone unless you weld it up yourself, and a BIG OB (i'd concur with Jas and say that a single 150 will be marginal when boat is loaded, esp if you replace all the camping amenities, so you're looking 200-250hp) will be thousands more. twins? double everything $wise.....impeller for a 200 prolly costs abt same as for a 150.
and your fuel bill with twins might need to come with some K-Y......
not sure about your climate in fortuna, but if winterizing is not going to be the issue it would with our northern bretheren, i'd go with the I/o. will you be using in saltwater or freshwater primarily?
