Ok, I have been hunting all over this site for an answer and just can't seem to find one. Here is my story:
I recently bought this 1989 evinrude 225 to replace my 1977 evinrude 115, great upgrade. I checked everything over as best I could on the stand, noticed that the VRO was disconnected, started the motor, on mixed gas, that had apparently not run in 2 years. It started great and ran surprisingly well on the stand. We pulled the trigger and did the motor swap, but not before changing the water pump assembly. With the motor on the boat we decided to take it out for a maiden voyage. all seemed to be running great for us. We varied the throttle to just re break in the motor from its slumber. After about an hour of running it, the motor took off, we actually gained another 5 plus mph. All we could think is it has finally broke free and is ready. Satisfied we returned to the launch and went home. The next couple times that we went out, the motor would run good, never at that wot point we had seen briefly, but it was running good, then things started going down hill. after a while the motor would pulse, or surge, but never get above the 3000 rpm range. We figured it was going into the slow mode, but honestly unsure. We have been running the motor and every once and awhile it would just take off to that WOT area but never long lived.
I have replaced the fuel line thinking that could be an issue, but it never changed, I have checked t-stats and they are working, checked the overheat alarm to make sure that works (was a fear that the sensors were bad) even tested the sensors and that made no difference. I am running out of ideas, my last idea is to change the power pack, but wanted to see if anyone could give me a little insite on this. I had it arranged to go to a shop, but after looking at it the shop turned it away do to the fact that the motor is bigger than what should be on the boat according to the coast guard. Please Help, you guys were great before.
