93 Yamaha PRO V 200 Bogging during Acceleration

[captdwayne]

I purchased a 20' bass boat with a 200 Pro V on it. Been having trouble with the hole shot. Motor idles good and runs 5800 RPM. The compression is 118-120 on all cylinders and the leak down is about 10%-12% on the cylinders. Seems to be bogging on takeoff between 1800-3000. Any suggestions??? The oil injection has been removed and running Amsoil. Carbs have been cleaned two times and carbon reeds have been installed. I'm currently running a Yamaha 14 1/2 x 25M propeller.

Have you figured this one out? I have the same problem and same motor.

Thanks,

I changed props. Went to a tempest plus 25p. It needed more sprop slip during acceleration. I have one large pvs plug and all the others out. It spools up to 3100 rpms and goes. Its a great prop. See if someone can loan you one for testing.

I changed props. Went to a tempest plus 25p 6000 rpm and 26p 5700 rpm. It needed more prop slip during acceleration. I have one large pvs plug and all the others out. It spools up to 3100 rpms and goes. Its a great prop. See if someone can loan you one for testing.

Thanks.I'll look into a Tempest prop.

May be lean in low speed.try hitting the choke during bog and see if it takes off.also rminder if it bogs pushing up on trailer and you hit the choke don't knock off the winch stand.if hitting the choke helps send me a pm.

I wonder if I'm running too much prop? Triton sf21 (1700lbs empty) Yamaha 200, Yamaha 23" prop., no jack plate. I'm turning 5400 rpm's at 57mph. According to the prop calc I used thats 10% slip. I dont know if thats good or not. Once I get past the short bog it gets out of the hole pretty good. While I'm at it do you guys have a good method for removing a stuck prop, because I have one?

Thanks,

Yamahas and really all motors like as much timing advance before they start to get fuel and air. Make sure you have at least a 1/8-1/4 in gap between the throttle cam and carb linkage. It could also be a little lean off idle. Try 1/4 turn in on idle jets. I find with our reeds they like about 1,1/2 to 2 turns out.

Thanks Stan I'll check it out. I have noticed that when just hammer it instead of easing it on plane I don't notice the bogging nearly as much.
