bought 67' 50hp merc ser. #2119719 last year well maintained garage kept whole life. since 1st run on water, seems to reach only half potential. acts like its getting too much fuel and wont clear out. new plugs and cleaning contacts in distributor cap are about all i have done other than new bulb in fuel line. before messing with a lot of stuff i would like to know where to start. i've gotten a little scared reading some prev. inquires<br />another issue is no water out pee hole. impeller is new, i have not taken out thermostat yet. assuming that i can resolve this prob. is there potential relevance to performance prob. while forcing water into water pick up tube, water returns back into lower shaft: and with engine running with ears on water warms coming from prop center. i had discovered that prev owner had pinched pee tube under powerhead between cowl. however even since freeing that issue, still no water.<br />should i begin w/carbs or ingition. i also have extra ignition box for whatever that may be worth.<br />thanks a million. daddy needs to get little girl back on water sooon catchin' fish
