1986 Mariner 90HP Over revving

[Haynan]

As I throttle up in gear, engine pulls ok to a point and then motor starts revving like it's out of gear. Throttle back and it is still in gear and pulls until I throttle up some and then it feels like it's slipping. Any ideas? Thanks guys, the hub is spun. Any one know if I can get a new hub and press it in myself? It's a stainless prop, marked 18 pitch, but no brand or manufacturer name.

Your right, sounds like the prop is slipping.To check this remove the prop ,get a punch and mark the inside spline part of the prop and them put a mark ont the allum.side of the prop . Take it for a run and see if the marks don't line up anymore.

Haynan,<br /> Sounds like you have a spun prop or loose prop.Check the nut and lock ring on the prop shaft.Check the condition of the prop also....

Haynan <br />That was amazing! You answered your own question and found the proper solution too. Wish I could do that all the time. Good Luck,
