Re: what type of engine was in my boat
the only engine I found listed for a 1990 Sunbird 175 was the 3.0/OMC cobra combination.
as Don and many stated, do not look at the 470 - you cant even polish that turd to make it a shiney turd.
if you really want to dump a lot of money into the boat, then look for a 3.0 liter and mercruiser outdrive. however by the time you get the boat splashed, you will have spent enough money to buy a 19' SeaRay with a 5.0 V8 that you can put on the water today.
