Re: 92 model Evinrude XP 200 question.
I see a couple of things here. The water pressure should be monitored by a pressue gauge, not by the overboard indicator. That is only to tell you water is indeed going through the motor. The gauge will tell you how much.<br /><br />I believe your boat has a pad and a step (notched transom). If so, the motor can be run higher. Thats the purpose of the step. <br /><br />If you lowered the motor and the top speed fell off we can assume the top capeable rpm's fell off too. That may be a problem depending on how far they dropped. We dont want to lug that motor.<br /><br />Since the motor is lower, now is a good time to get a baseline on the water pressure for future reference. As Kenny suggested I would throw a new pump kit in right away.<br /><br />Gas thats 6 to 8 months old has probably lost some octane. Adding 15 gallons to it only means you have 15 more gallons of gas that needs to come out. Use fresh 87 octane only. Even adding 93 octane to what you have doesnt raise the octane level. It doesnt work that way unfortunately.<br /><br />Those looper blocks have quite a large water cavity so it may take some time before you see water out of the overboard indicator. Your pressure gauge reads pump pressure so it will start to register slightly before you see water out the indicator.<br /><br />Since the motor sat for an extended period and runs rough I would suggeat cleaning the carbs. A partially clogged jet can cause a lean condition. Pistons in a two stroke dont like that.<br /><br />Just an FYI (I'm sure you already know this) -- use Champion spark plugs only.<br /><br />Good luck!
