bolts, it’s easy to replace.

The exhaust elbow at the engine, it can get constricted - like an
artery. Which restricts the ability of exhaust gas to get out, thereby
cutting your RPM.

When I had a similar problem, we found the propeller was totally fouled -
even though the bottom wasn't that bad. A prop that is nothing more than a
wad of sea food is not good for motoring. Would count for the vibration and
lack of performance.

Just my 2 cents, but if you have a folding prop it might be a good idea to
check that the two blades are freely moving. This could explain the vibration

Hi Jackson,
As Joel points out... exhaust smoke is a key indicator here.
If it doesn't show black then we usually can rule out and
overload/overfuel problem (fouled prop, fouled exhaust mixer, fouled
air filter, etc.)
A clean exhaust and not making RPM is hope for the best and change

Black powder, rubber smell and charge light point to a loose or defective drive
belt. Could be a rusty engine drive pulley causing the belt to wear. Not
unusual in a boat.
The running problems, vibration, low rpm etc. could be a fouled prop. Plastic
bag, line or mussels. At least have a close

If you're not getting to max rpms, there could be a number of issues:
1. Fuel filters clogged and need replacing
2. Injectors clogged and need servicing / replacing
3. Air filter - already noted
4. Elbow clogged
5. Someone monkeyed with the throttle adjustment?

Inability to increase revs could also be caused by a partially blocked
elbow.
