I have strong reverse thrust to starboard. It renders me nearly out of control. Are there any fixes for this?

Prop walk

What you are describing sounds more like starboard prop walk. More than likely you have a YS-12 series Yanmar with a left handed prop like mine. If you also have a 3 bladed prop, that will cause more prop walk. When backing, put the wheel hard over to port and that will compensate for the starboard prop walk. Practice using that prop walk to your advantage and you will soon find manuevering far easier. -Roland s/v Fraulein II

Greg: Contact Bay Prop in Alameda, CA. and ask for Bob Kilian. Think he only works on Tues - Fri. Talk to him about a Non-slip tip Prop. The price for redoing a 2 blade is about $130. You will find that this prop is going to give you better thrust in forward, more control in reverse and will help with the Prop Walk. You will need to transmission ratio, the engine model and horsepower rating. This is a good solution for ANYONE without deep pockets and prop problems.

backing the H30.

Greg - I also have a H30 w/ YSB12 Yanmar. It is true that there is substantial right prop walk. However, with a little practice this can be a strong advantage in docking and manoevering. I almost always now back into my berth and have found that the boat backs well and predictably. If you would like I can show you how better than explain it. Give me a call, I am in Lighthouse Point. 561.395.5984 Henry

Reverse

We also discovered that once we got used to it the prop walk was very predictable. Ours is a different model and backs to port. We cruise extensively and it is nice to know that coming into a strange dock for fuel etc we know what will happen. Someone posted recently that they had tried the "winglet" prop and ther was no noticeable improvement. You might consider a three blade, that did reduce our prop walk.

Pulse the engine

Use healthy bursts to get the boat moving and give you steerage way, alternating with longer periods in neutral, or minimum throttle to steer with out prop walk. Practice - after while, we figured out ways to get the propwalk to work for us. That means working starboard turns into your routine while maneuvering. Shock cords from the tiller to a cleat on the side of the cockpit take the strain while cruising on the engine. David Lady Lillie '77 h27

countersteer!

My 81' H30 has a wicked port prop walk. It will generally rotate the stern 90 degrees to port before the boat has enough speed to regain rudder control. My solution is to pulse the throttle as mentioned and before I want to back the boat I simply turn the bow to port 70 to 90 degrees, so the rotation simply puts the boat back in it's original direction.

Compensate

On my 356, the bow veers sharply to stbd when I apply reverse -- unless I compensate. I went out and practiced coming up to a mooring until I figured out what to do. If I'm at a standstill and apply reverse, I start with the wheel 1/3 turn to stbd. If I'm moving forward and want to back down, I turn the wheel 1/4 turn to port (and then to stbd once the weigh is off.) I can back as straight as I care to now, and I also know that I can use the thrust to cozy up to a pier on the stbd side if I care to. I can also use the veer to counteract a crosswind. So, don't fight it, learn to control it and work with it. Makes you feel pretty competent, too.
