Voyager Performance Problems

Randy, I've owned an 86 Voyager for about three years now. I've got the thing looking pretty good and now I'm going to try to get it to go this coming season! The boat is in storage right now, but hopefully I can give proper detail to get some feedback on setup. The motor (engine) is an Evinrude 150, which I believe to be original. Last year I added a jackplate with 6" setback. I believe the make is an "Off Setter". It currently has a Raker three blade 14 1/2 X 22. I have not GPS'd it and have only gone by the speedo. Tach says 4200rpm @ about 42 mph. I can probably turn more rpm, but it feels like I'm not gaining any speed as I've trimmed it way up. Motor seems to idle just fine, never fouls plugs, I mix the oil as the injector was removed before I owned it. The prop centerline is about three inches below the pad. Not sure how much more I dare bring it up? Very hard to get on plane when I hammer it, can't even get a skier up using this prop. Dual cable steering, hull is of the XT type. Seems like the throttle response is only first half. Second half doesn't do anything. Anyway, if you have any ideas on where to start, let me know. Kraig



From your description it sounds like your prop is way out of whack. It is not lifting the boat and no amount of power is going to push it faster till we get it free running. The bottom could be soft and "power hooking". That would be bad. The motor could be dropping a cylinder under power and that would explain the poor hole shot and top end. These are some of the possibilities and they should all be looked at. The gearcase height sounds ok. A 22 Raker and 150 OMC on a voyager should run 60+ at 5500rpm+. Have these things checked and see what you find. It will be very obvious when you find it as the boat is 20mph off right now. 

Hope you find the problem,
