150 Yamaha RPM's Bob P. Something just came to mind about my RPM problem. I purchased this Grady last year in the fall. At that time my mech. Marty changed out the cables for me, as the ones on the motor were TACKY to say the least. :idea: That could be the problem, adjustments. Will check...

Will do Bob. Be next spring or early summer. Thanks ALL ........ :)

Thanks Bob and Grog, I will check the throttle plates in the near future Bob. Other than that I guess the best bet would be wait until spring, and let Marty, the mechanic, check it out and come up with a solution. Want to thank you both for your input, much appreciated. :)

Bob, It looks like I have about 1" above the blade edge before it would hit the engine. I have pictures of the prop, and could take more if you needed them but do not know how to post them here.

Bob P., I measured the prop from the center of the shaft to the outer edge of one of the blades and read 7" As for the throttle plates, that will take a little time to check. The boat is somewhat closed up now for the season. BUT, thank you for the input. I may just have to wait until next...

Thanks Rob. The boat is now out of the water, the engine has been winterized by a Yamaha mechanic. I mentioned this to him and he said he would have to take it for a ride and check it out. (next year) He is also a friend. STRANGE...... It didn't struggle to get up on plane, and sounded GREAT...

Grog and Bob P, Thanks for the reply. Not sure what the prop size is actually. It is SS, not the polished kind. There are two numbers on it. One is "17M" and the other is "B 90184" I measured the Dia and it appears to be 14" I took some pictures of it but do not know how to post them. If I...

Not sure Grog, I will have to check it out later today and get back. Boat not here where I'm at right now. Thanks for the reply.

I know this has been discussed before but I need to ask anyway. I have a 1987 204c with a 1987 Yamaha 150 on it. Question: At wide open throttle I only get 4500 RPM's The engine runs and sounds great, just not the RPM's I think you are supposed to get. The speed at 4500 by the GPS is 30. Any and...

Looks real nice Pete. Thanks for your input and the nice pictures. Good luck and have fun on splash day.

Thanks Pete, The pictures are great. HMmmmmmm, no wax yet? Mine looks like that (on one side) after compounding and then waxing. Lot of work, but worth it.

Thanks Bob. I do understand about the anodes. unfortunately the ones on this Yamaha 150 are small. One on the bracket is 7/8 X7/8 X 1-7/8 and the trim fin. Thats it. I will be able to check on them very easily.

Thanks for the input Pete. The idea with the tape sounds like a good one. I think I will strip the old paint around the motor bracket, tape it like you suggest and do the bottom. Then as you said do the bracket. Feeling much better about this project after checking with you folks on this...

Thanks for the input PlymouthGrady, I did in fact go to that thread and got the info I needed, along with BobP above. Thanks again,

Thanks for your input Bob. So you say that the Pettit Hydrocoat is OK, just keep it off the engine bracket and lower unit. (keeping a close watch on the zincs will be a must, correct?)

Good evening, I'm sure this has been asked before but I don't have a clue on how to find it. I purchased a 1987 20' Overnighter last fall and need to paint the bottom. It has been painted before but is in need of another coat. When reading the owners manual for the 150 Yamaha, also a 1987, it...

Hello All, I appreciate all the replies you have made over the last few weeks. I am in Florida at the present time, relaxing. When we get back to MA I will once again get working on this bottom painting job. Thanks again folks appreciated. :D

Re: The measurement Thanks, I'm not sure if I answered you about the measurement you got for me. That is just what I bought as a replacement. 1/2 inch. THANKS AGAIN,

Chris, I checked with Boat US for insurance on my 1987 204C and after talking with a agent was able to get him to admit to me that Boat US doesn't offer "Waiver of Depreciation" He didn't want to tell me that, kept beating around the bush. You CAN get agreed value, yes, but what happens if...

Duh! Hello Scott, Just started looking around and found your picture here and what engine you have on the boat. Disregard my rambling PM. I can see that it's a lapstrake boat. Looks really great. I don't know how to put up pictures so I have not. Be talkin to ya, :oops:
