Bravo 3 Clunk Noise-gctid372199

[Guest]

I have a 2007 246 and was fishing in Lake George this past weekend and sometimes but not always after I put it in forward gear and started to give it more gas there is a single bang you can feel. No other noise other than that. When I put it into forward gear you could feel that the drive was in forward motion. It is only when I was giving it more gas that this happens.

I was just reading some other threads on Bravo 3's making a noise and is hopeing this is not the same problem.

Any Ideas?

Thanks for any ideas

Do you get any propulsion at all?

I hope it's not your coupler

my first thought is a broken tooth on the bull gear on top of the drive.....

When I put it in forward gear you can feel the boat move. Only when I give it more gas is when I get a single bang.

The boat gets up on plane fine and wot is normal.

I am assuming it is the outdrive but maybe an engine mount gone bad?

Thanks for the feedback

i used to have that noise on a cobra drive i once owned,what the noise turned out to be

was...if i had just reversed i guess the leg would just slightly hang up and when i put the boat

in forward the propulsion from the prop would slam the leg back down against the transom

and you would hear and feel the bang you describe.I dont think my leg used to get hung up

very far either but definatly enough to make that sound.

What do mean by the leg?

That is what I was thinking too.

Needs the cables adjusted

I do not think it would be a broken tooth as it knocks only once then it is fine.

No other noises once it has happened.

I am going to try it again with the engine cover open this weekend and see if I can pinpoint it.

Thanks for the comments

Sometimes the "clutch cone / dog" (depending on unit, you have cone) will not be indexed all the way in, in idle and when you throttle up, it will either slide the rest of the way in, or "slip" a notch and engage. These "teeth" (for lack of a better word) are slightly angle cut to hold in under load and the slam is it sliding in.

Usually corrected by cable adjustment, as PP stated.
