I have an Evinrude 9.9 on my boat. It works great in foreward..lots of power and pushes the boat along fine. The trouble I'm having is that there is no power/torque in reverse, it will not back the boat out of the slip. Has anyone experienced this problem or have any insights?

reverse?

How long do you leave it in reverse? Initially, reverse will "prop walk" in that direction, usually stern to port, then water must run across the rudder for steering to be accomplished, then reverse will be noticed. Could take several seconds, 10-15 maybe. Also, unless your outbourd is directly behind the stern, it must overcome the stern off set. It is typical, and gets more noticable with more horse power. Practice, practice, practice. We only due it once a boating day. Good luck!

Shift linkage maybe...

Are you sure that your O/B is actucally going into reverse gear, and not staying in neutral? The prop may turn, but have no power behind it. This could be a linkage adjustment issue - simple to fix. On my Johnson (same as Evinurde), this adjustment has to be made after dropping the lower unit, for example when the impeller is replaced. Try putting the O/B in reverse, and then turn it off. Disconnect the plugs, and/or kill switch to make sure it can't start, and then see if you can easily turn the prop by hand. If so, you either have a lower unit problem, or the linkage is out of adjustment. I hope this helps. Michael H26

Outboard propeller

Hi! Earlier in July, we spent 5 days on our H26, & also noted the reverse was lousy, especially if the breeze was up. We have a 9.9 Nissan. When we got back home, I did a bit of research, & decided to change the prop. The diameter was 9.2", & the pitch was 7.8". I did not have enough room for a larger diameter, so I purchased a new prop ($90 Can.) from Nissan with the same diameter but a decreased pitch of 6.1". I tried it this weekend, & was pleasantly surprised by the difference. By the way, you can determine if your prop is working in reverse by shutting off the motor, leasing it in reverse while the sails are up, & seeing if there is any drag on the motor. Chances are, however, that the problem is the pitch. As the Nissan agent said, the prop is not biting enough of the water to adequately propel a heavier boat (compared to a small fishing boat). Good luck! Rick s/v MoonGlow

Evinrude, too...

I have a 1999 Evinrude 9.9 4 stroke, long shaft, high thrust, electric start, remote steering, with 12 Amp. charger (to make sure the model is the same), and it backs the boat great. In fact, If I have to get away from the dock in a cross breeze blowing me into the dock while single handed, I don't hesitate to back away because it is sometimes hard to get the bow into the wind. I've built a simple tie rod to connect the motor to the rudder for better manuverability in tight quarters and that helps a lot. It was very easy to connect the motor using the existing hole usually used to mount the optional tiller. Fair winds, Tom

I also have plenty of thrust....

...on my Johnson 9.9 Long shaft, for backing the boat. Like Tom, I have linked the O/B to the rudder, and it makes directional control when backing a breeze (back-in docking is a simple one person job). Even before I added the linkage, there was no lack of reverse thrust though. Let us know what you find... Michael C. H26

Just came across this

power thrust video from Honda. They claim 60% more thrust in reverse with their exhaust relief gas system, which passes the gas through another port when in reverse, instead of through the prop. Maybe that explains your situation.

Thanks guys

I checked the prop and it does not seem to be moving on the hub, then checked the linkage,it is very hard to see all the moving parts without taking the top off the motor, but I was able to follow it through to where I found a stop that came into play when reverse is engaged. It apparently is to stop the throttle from opening too far in reverse, it was adjusted all the way back so I think there is likely some slack in the linkage somewhere but since I'm the only one who uses the motor I just removed the stop and now I have lots of RPM's in reverse. It's probably the easy way out but it'll be O.K. for the rest of this season. Thanks to all for your suggestions Craig S/V Wind Toy 1977 H25

I think the limiter is for neutral...

I'm not at my boat, but I believe that the throttle stop limits RPMs in neutral, which is an unloaded condition, but should not limit it in forward or reverse. I think you throttle limiter or shift linkage probably needs adjusting. Interestingly, the throttle was being limited in forward on my O/B when I bought the boat, and I had the dealer correct it. Mine is a Johnson - same as an Evinrude. In any case, I'm glad you got it working. Michael C. H26
