"I have a 1956 30hp Johnson mo

"I have a 1956 30hp Johnson model RDE-18. The motor sat for about 3 years. I've changed the plugs. I placed a new cork/rubber gasket on the fuel tank, cleaned the fuel lines and bulb. I changed my normal fuel mixture of 1 qt non-detergent 30w oil to six gallons fuel to a 24:1 of Quicksilver premium plus tc-w3 and 89 octane. I ran the motor in a trash can and it ran fairly well. Quite a bit more smoke that usual. I was able to adjust the slow speed idle to smooth things out.
With everything checked I took it to the lake. It ran quite well for about 15 minutes. I had gotten into some weeds. I slowed down, shifted to reverse to clear the weeds. Back in forward the motor seemed to struggle getting out of the hole. I pumped the prime button to get more fuel but nothing. After running at idle for a few minutes, I attemped to get on plane. She jumped right up and took off. I continued to idle down and power up for about 20 minutes with the trouble coming about every 4th try. On my last attempt, I had slowed down to clear more weeds. When I went back to forward, the motor reved up but boat was not moving much more than idle speeds. I backed down on the throttle and idled back to dock. Long story short, I've reviewed postings and believe that I have a bad clutch dog. Could the lack of power be in any way related to the clutch dog or do I have another issue."
 
"I have a 1969 55 hp evinrude.

"I have a 1969 55 hp evinrude. It starts great and runs smooth in the yard with a water hose hooked to it, the electronic gear buttons seam to work fine , I can shift into forward or reverse and see the prop change direction, and I can throtle up and it revs up smooth in forward & reverse. However when I put it in the water, and as soon as I put it in reverse you can tell it goes in gear and then it stalls out, and when I put it in forward it goes in gear but will only run at idle speed, when I gas it up, it will not go any faster but does'nt stall out. Any comments or info would be helpfull. Thanks Gary"
 
"I received my service manual

"I received my service manual today. Before I dig into this job, could someone please let me know if the clutch dog is the likely culprit to my issue. Your help is GREATLY appreciated."
 
FYI: After a bit more researc

FYI: After a bit more research I may have found that my problem is not the clutch dog but rather a bad propeller hub. I took the cap off the shaft. Replaced the pin with a screwdriver and applied a little pressure to the prop. I was able to move the prop with about 15 lbs of pressure. I will be taking the prop in to have it rebuilt and will not be messing with the clutch dog.
