I just purchased a 2006 Honda 40 hp (4stroke)with power trim. It has not yet touched water. We attached the hose, started it up, waited 5 minutes, and went to put it in gear. It did nothing but grind. I called the dealership that we purchased it from (and who installed it), and the mechanic said we had to get it into gear quickly. I am not comfortable with this. I owned a 40 hp force and grinding was never part of boating. Any ideas
