I have a 1999 Crownline 182BR with a Mercruiser 4.3L mated to a Mercruiser Alpha One Outdrive. The problem I'm having is there is a low pitched roar coming from somewhere betweer the back of the motor and the outdrive. It sounds kinda like a dry bearing and it's pretty loud. It makes the sound whether the boat is in nuetral, in gear, trim up, down, or level. Another problem which may be realted is when you put it in reverse, the motor bogs down and dies but it will go in foward fine. The boat had a new crate engine installed last August and it was done by a boat shop. It has been ran for 6 hours on the new motor but this year it's been giving me problems.
Any help would be greatly appreciated.
