I have a 13' GLS with a 30 hp mecury motor on it, but it just crawls with 3 people in it. The RPM reading is only 3100 though the motor is rated to 5500. Sorry I must confess to being a newbie.
Is this a problem with the motor not getting enough gas, a bad tachometer reading, or the prop which has a few dings in it.

It could be any of the problems you listed or a combination of two or more of them. Most likely is your engine has dropped a cylinder.
How does it perform with one person?

It actually seemed to perform great even with one person, but with 3 - 4 people it barely creates a wake. I didn't take it out again by myself to see if it was the load, or if something had gone wrong since I was last out.
I imagine the load of 3 was roughly 500 lbs.

Blag - I had a 13 with a 25 on it and with 2-3 good sized people, it would plane, albeit it might be a tad slow in getting up on plane. I suspect that your prop may be the wrong size/pitch or your trim is not set properly. You might consider experimenting with the engine trim. It might also help getting on plane if one or more adults move aft a bit until it comes up on plane. ----- Jerry/Idaho

B, check out the prop first! Sounds like severe "overpropping" (pitch too high)!!?? If so, this lugging can damage engine! Happy Whalin'/// Clark... Spruce Creek Navy

I owned a 1989 13 sport bought new with a 30 Yamaha. With myself (210 lbs) passenger (125 lbs), I could pull a 165 lb skier up and tow him around effectively It sounds like either a motor problem, or prop. The difference is so dramatic with light and heavy loads, I suspect something's awry with the engine itself.
