hey beans,
i've got an 88 45 hp merc that i troll with quite a bit. the problem is when i go to run acroos the lake it can take 1-2 minutes or longer to buildup rpms. once it does it runs 52-5300 rpms and 28-30 mph. i've noticed that when i troll all the way to the ramp and and load there is an oil/exhaust? sludge? that drains from the upper and prop exhaust. can this be cured or is just part of low speed trolling?

You mix anything in your gas like lucas, sea foam, or a like product. When was the last time you did a decarb. That is common on those motors.

i use stabil in the gas only, with the oil.
is there anything else i should use for the gas?
decarbing will be on my next trip out.
are the lucas ans seaform in tank gas treatments?
i've read about the decarb process on here before just haven't done it yet. where can i find the right products and are there any processes or problems i should be aware of/
thank

You can get the sea foam at Auto Zone they have it in both (can is called sea foam)(spray is called deep creep) they are the same thing. I run half a can to 12 gallons in every other tank of gas. I would run it in every tank but it gets a little expensive when you fish almost everyday. If you decarb on the water make sure you ideal is you are feeding the sea foam through the fuel line. Once you are done run it at WOT. One down fall to decarbing a motor that is trolled alot you can dislodge stuff in the carbs and cause a jet to get clogged resulting in the carbs needing to be rebuilt. But that is better than having to rebuild the whole motor do to carbon.

maybe i'm misreading it but you put seafoam directly into the gas?
or feed it into the gas line?
are these 2 different treatments?
i rememberr reading about using the spray. it goes into the carb intake with the motor idling until it bogs the motor down or stalls it then you run wot until the smoke quits.
i'm i mixing up 2 different things/ would it be best to run the gas treatment for awhile then use the spray on it.
sorry for all the question marks but i want to get it right.

There are several ways to use sea foam just whatever you prefer. I (and I am not saying this the best way) get a separate one gallon gas can and put one full bottle of sea foam with one gallon of gas. Let the boat ideal the mixture out. Then I remove the plugs while the motor is at operating temperature and spray deep creep into the cylinders. Put the plugs back and let is set for 15 to 30 minutes. Then I run it at WOT and 3/4 WOT for a ways. Rarely do I use deep creep into the throttle bodies for a decarb. I use to but have since stop because it does not seem to work as good for me. The only time I will spray it in the carbs is if after the above treatment I think it needs a little more. Then I just flood the motor out with it. If you troll alot you can put sea foam in your gas as a treatment or lucas fuel treatment which ever you prefer. There are many others on the market but the two I mentioned have been around for thirty or so years and are proven to work, at least to me anyways.

Where are you located at I might be able to help you out if you catch me one of these weekends.

ran the treatment out back today. smoked up half the neighborhood. good thing it's a holiday. haven't been on the lake yet but it seems to be runnimg smoother and i'm gonna have to turn the idle down some if ti stays like this.

They will smoke like crazy but that means it is working.

may have clogged the carbs. i'm going to try a second treatment before i rebuild the carbs.i may not have run wot long enough, just 1.5 laps on hefner they were done just 2 years ago and the boat is not run that hard. also looks like i may need new fuel pumps and seals noticed a small leak on the upper carb and if i've got to dig that deep for the carbs i might as well do it all.
also, i noticed that you do the occasional used motor trade. i would like to get a 65-75 h.p. on this boat. the 45 just doesn't have the power when i'm carrying a bait tank and 2 people plus gear. would need to be an 80's or 90's model and trade on the existing.
thanks again

Merc, OMC, Suzuki, or Yamaha. Tiller or controls.

controls on both (tradein and new one) merc but not real picky would look at anything for the right price. would also want you to do the trade out/ install on them. let me know what you've got and estimated cost. i know it would depend on seeing my motor.
thanks
