Have a 1974 SRV 190. Under normal throttle all is fine once hit about 3500 to 5000 rmp steering gets extremely tight. Almost takes two hands to turn the wheel. Any idea why this would be happening?
I/O. Will take some pics and post later today. Had original 188 in when i got it put new engine in currently right at 300 hp. Boat flies problem is WOT extremely hard to maneuver the boat as the steering is so tight.
Do you have power steering, most I/O's do? Either way, turn the back of the trim tab (on the cavitation plate) all the way to the right, if your prop rotates clockwise (most boats do).
If you have power stearing check fluid and if proper fluit level is there bleed system . If it worked befor it show not have anything to do with the new engine.
