I have a 1986 Bayliner with a 2.3l Volvo on a 275 Volvo penta outdrive. My problem is that it looses power when i get more than 2 or 3 people in the boat the bow of the boat just stays up it wont plain out and it just seems like it has no power. I have had it about 6 years and it just started at the end of last season and the start of this one. I am open to any and all sugestions to what the problem could be. I was also wondering what if any other engines would bolt to that outdrive. Thanks for the help. Brad
