70 HP motor seems underpowered. How do I troubleshoot.

Thanks for the info.

I have a service manual but it's a text based.

I'll try try to find a YouTube video to explain the process.

Once he gets those cables adjusted he will be looking for a prop, that small prop will make that 70 scream on a 16' boat. LOL

If anyone has a similar motor and can take a picture of how the linkages are routed it would be appreciated.

Hi,

cables put back they way they are supposed to.

Just hoping for a somewhat warm day this week to take it out for a test drive.

Thanks for the help,

Alex

I managed to get the boat out this afternoon. The water was a bit choppy but I managed to get it up to 35 MPH.

The ride was wild I thought the boat was about to tear itself a part.

There are five holes to set the tilt of the motor. Initially the motor was in the 4th hole away from the stern. I could not seem to get the boat to plane. The bow would not seem to go down at speed.

I then tilted the motor to the 3rd middle spot and things seemed to be better. It still took a bit of time for the bow to drop.

I think I will have to play around with it perhaps there is another configuration that will drop the bow down faster.

Thanks

The closer in, toward the transom, the faster the boat will plane.
Always a trade-off as you will lose bow lift and speed if you go too far but you will figure this out pretty quickly.
