Question about Boating

1 Answer

I have a 1978 Steury boat with a 165 hp inline six cyl Mercrusier. Problem is the steering. it pulls to the left hard no matter how I adjust the little fin on the bottom of the out drive. And from a stop if I give it the gas it will take the wheel right out of my hands and spin all the way to the left. It's really dangerous. What can I do to fix this problem. Everyone tells me to adjust the fin on my out drive. This does nothing at all.

The propellor can cause transverse thrust and the heavier the prop the greater the sideways pull. There are other factors like blade width and trailing edge cup. Is this the right prop for your boat? Some legs have a tension adjustment on them, and try that little fin again the other way,just one more time. Cheers Timo.

How To Change A Fan Belt On A Jeep cherokee 96

That depends on which engine you have. On v8 engines you need to put a wrench on the tensioner pulley and pull it over. On six cyl and four cyl engines there is an adjustment bolt on the power steering pump. Loosen the pump slide bolts and turn the adjustment bolt that moves the pump in and out of adjustment. (bolt runs under the pump...long threaded rod with a bolt head)

What role does the trim tab on an outboard play as far as handling and hard steering, and how do you adjust it?

If you are talking about the small tab under the cav. plate.Its job is to counteract the effect that the prop has on steering.Because the props. spin in one direction,they create a sideways pull on the motor due to the prop biting into the water and trying to pull all with it.2 motors on the 1 boat often have a different gearbox fitted,and one will spin in the opposite direction and this counteracts torque steer.To adjust yours,work out where you drive the boat most.Speed etc.Higher speeds have more effect.If it pulls right,adjust it left.One bit at a time.I think yours will have an allen key or hex screw above the tab.Loosen it,move the tab.Takes only minutes.I hope this helps

My mercury 35 hp outboard motor idle's fine but won't run

While at the river try to adjust the fuel air mixture. When you are on the water it puts the engine under a load and if that dont work then dont be afraid to bump up the idle stop screw slightly.
