Speedometer Tube

[legalfee]

I have a 1995 Force 90HP. My speedometer doesn't work and the tube looks like it's going into the lower unit. Is there a hole down there that is possibly clogged and can be cleaned out?

Assuming it's like a sterndrive lower gear housing, there is a notch just above the torpedo/bullet nose. It's common for these to plug after striking wood trash. Most plugs can be dug out with a 1/16 - 3/32" drill. Any drill large enough to enter the hole behind the notch without enlarging the hole, or jamming and breaking off. A cordless drill with a gentle hand will remove most plugs. The gentle hand will keep you from drilling too deep into the aluminum at the back of the hole.

I did find this YouTube video: https://www.youtube.com/watch?v=HBwbhepaCAc
It's a Yamaha motor but the same principle.

Sometimes they get clogged and sometimes the hose/fitting breaks inside the drive.
You can add a pitot tube and adapt that to your hose to the speedometer.

I trimmed the motor up as far as it would go and I could see the tube. I'm going to have to get it out of the water to get to the hole.
