Evinrude 9.5 and 14' Alumacraft Model AL questions

Hi guys, just picked up a 1965 Evinrude 9.5 for my 14 foot 1960ish Model AL Alumacraft. Being my first outboard (hell, first boat) I'm looking for any and all suggestions on what I should do to make sure that the motor is in tip-top shape, and any suggestions or tips on operation.

Some info: I took it for it's first run tonight. Seemed good enough, but I guess I don't know what to expect. The boat hit 13mph on the GPS at full throttle with me (230 lbs), a full tank of gas (6 gal), electric trolling motor, and 27 series battery on board. Does that sound about right on a 14 ft boat? It never got anywhere near planing out on flat water, don't think I should expect that but it's worth mentioning. The battery and trolling motor were up in the bow, gas/motor/me obviously to the rear. I did my best to balance the weight out.

Also, I could get it down to about 2.2 mph at it's slowest, and it pretty much wants to die on anything lower than the 'shift' setting on the tiller handle. It's awfully shaky at lower RPM.

What type of performance should I expect out of it with the boat I have? Any guesses on what speeds I should be seeing high and low? Should the motor shut off when the tiller handle is put all the way to slow, or should I ideally have to hit the 'stop' button to turn it off?

Any insight on this would be great, as I couldn't possibly be greener with this stuff. Thanks guys.

Re: Evinrude 9.5 and 14' Alumacraft Model AL questions

I'll try to give you a few ideas as best I can.
1. I weigh 230 lbs. and on a lightweight aluminum boat a 9.5hp OMC will plane me out and go about 18 mph. (but just barely plane me out) So with the trolling motor and battery, it might be doing as best as a 9.5 will do. If your boat is fairly lightweight with no load but you, it should plane it. Try taking the cowl (cover) off the motor and run it and see what happens. Sometimes those motors have exhaust leaks into the engine cover and it chokes off the motor. You won't reach full horsepower until your boat planes out and the motor is able to reach higher rpms.
2. Ignore the markings on the throttle handle---they're useless. There should be a throttle stop that would have it fixed where you could idle with the throttle on low, but the stop is made of plastic if I'm thinking right, and they are commonly broken. Without the stop it will die when the throttle is fully closed.
3. If your powerhead is really, really shaky you probably have a broken motor mount which is also common on the 9.5's. THere should be some flexibility side to side and front to back, but not sloppy.
4. Since the motor is new to you, changing the water pump impeller, fuel lines, and cleaning the points and rebuilding the carb is always good insurance.

I hope this was helpful and that you enjoy your new boat. Welcome to iboats.

Thanks for the tips.

-The cover on or off doesn't make a difference, I believe that the seal is OK.
-I did check and the throttle stop is still intact and functional.
-The powerhead isn't shaky to the point of something being broken, I think it's just due to the fact that it's dying out at low rpm.
-I've changed all the fuel lines and plugs so far, Impeller is on order, and unfortunately I know diddly squat about carbs so fiddling with that might be a bit scary unless there is a step-by-step writeup on here somewhere.

Does at least the top end speed look OK, or is it not what it should be? Should it be dying out on the slow setting, or should I need to use the button to turn it off?

I`d say your speed is in the ballpark for the 9.5, the settings on the throttle handle aren`t really matched up exactly so there just kind of a reference. It will die by itself if the idle is set to low.

I'm sure that if the idle is set too low it won't run, but I really think it's shutting down earlier than it should. Any ideas, or should I just say screw it and go through the carb and ignition systems?

going through the carbs and checking the ignition systems should be good, slow speed knob, turn all the way in (carefully and slowly) and then come out 1.5 turns might work, but sounds like the carb is really gummed up.

also, change the whole water pump, not just the impeller. there is now a SS insert inside that plays nice with the new impellers.

parts here, and diagrams as well, could not go any further without a model number, sorry.

pictures of the motor and boat would be nice too............. especially the transom :cool:

I know the model number is a 9522, and I'll get some pics for you today.
