280 VOLVO PENTA /OUTDRIVE

Question
SLIPPING IN GEAR FWD AND REVERSE

Answer
Hi Jon...Thank you for selecting the undersigned to reply to your question.

I'm not a mechanic, however, the symptom suggests you may not be completely shifting the throttle lever into gear, or perhaps  the shifting mechanism is defective and requires adjustment. On the other hand, there could be a problem with the pinion gear and carrier bearing. Best you consult a qualified and reliable marine mechanic, and there's one with AllExperts.
