Re: 85-140hp out of the same block? How?
Ha ha ha, Dhadley,<br /><br />Naw enthusiasm will not change my testing. However, old man winter has pushed it onto the back burner, or completely off the stove.
<br /><br />My engine set idle for about seventeen years without winterizing or any type of care. It was garaged for five years until I move out in the country. There it sat in my back yard for twelve years. So, this past summer I bought a new boat and kept the old 1985 motor and trailer.<br /><br />Before starting the engine after the long siesta, I replaced the water pump, thermostats, and the lower unit gear oil.<br /><br />After determining that the VRO was not up to par, I replaced it with the latest four-wire version including the tank and hoses.<br /><br />The engine starts and idle just like when it was new. However, until it completely warms up it is a little temperamental. It does not take full throttle, although it will take full throttle after a couple of hours crabbing, or trolling for fish. Although it would accept full throttle I did not keep it there over a few seconds because, I was afraid of running lean and blowing a piston. I just used it as a fishing boat and slow poke trolling this past summer.<br /><br />I will pulled the carburetors this winter and rebuild them. One question, are all the carbs the same or there a primary and secondary carb?<br /><br />After the engine is running right and a baseline is established, should I lean towards a four-blade prop, or a three-blade prop? Most of my boating will be in the Chesapeake Bay, where I will encounter a few chops at times. I do not usually go out in rough water. But, I can be caught out in some rough stuff at times.<br /><br />As for the compression, I took it when I first started the engine; it was about sixty to sixty-five across the board. After running it for a while and doing a decarb. I took another test and it was at 114-115 across the board.<br /><br />Take care, and enjoy the warm weather you guys are enjoying down there. <br /><br />Regards,<br /><br />DoferGofer
