Tilt Problems

[kamboat64]

1998 Force 120. Hit something on bottom of lake underway. Wasn't going very fast. Maybe 15 mph, but fast enough to knock the motor up on its tilt. So now, my tilt up doesn't work under power. Works fine sitting still in and out of water. Just not while moving. You can see it trying to tilt up but it moves slightly and then sort of falls back down. On trailer, I had my wife trim it up while I tried to hold it down. It worked great.

As always, all input and assistance is appreciated.

That blow probably blew the seals in the bottom of the pump.
The pic shows a good seal and the bad seal.
There are 2 in the pump.
These are the only part in the motor/pump that you can fix.
Trying to lift you vs the boat, the difference is thousands of pounds of weight and pressure.
The link below show how to get the valves apart.

Thanks Jerryjerry. Gives me something to do next weekend. Hopefully this is the problem. I'll post results once I'm finished.

jerryjerry....which ones would this be in the attached pic. I don't want to order the wrong parts.
Would that be the seal that is part of the #10 assembly? Thanks again for all your help.

398188 Briggs and Stratton carb seal.
On eBay
I think about any lawn mower shop or small motor repair might have them.​
