throttle slippage

[procraftmark]

I have a 1985 90hp rude, and my warmup lever doesn't stay up by itself it is fairly sloppy, but when I do have it up all the way it doesn't really throttle up much and when I am in gear and in reverse and full throttle it doesn't act like I am giving it any gas at all is the throttle slipping inside the control? On that control the screws seem to take it off the boat as one piece instead of loosening the cover, sure could use some help<br /><br />thnx<br />mark

Re: throttle slippage

Hey Mark...<br /><br />First, get a OEM manual for the engine. There is one screw that holds the cold start lever to the control box. The screw is probably loose. There are two screws that hold the box to the gun rail with nuts and washers, normallly. The box is not all that hard to disassemble but a manual would be a great help. <br /><br />Don't think the throttle is slipping because your control cables are "snap in" cables unless the cable core wire is broke. <br /><br />Here is something to look at with the motor not running. Shift into forward and give it "full throttle" (have someone spin he prop while you shift). On the starboard side of the carbs is a pin (starboard is the drivers side). At full throttle, is the pin staright up and down?<br /><br />A question or two. <br /><br />How long have you had the engine and is this problem a new one?<br /><br />Let us know what Ya' find.
