    25hp carb to 30hp carb on 1999 Johnson

    Would the revs go above the WOT,or would the extra power be more torque? If a car or bike engine is given more power,it is converted into more revs,but more revs on an outboard have a limitation. Without a change in gear ratios,wouldn't a power uplift be over revving the motor?

    Clinton chief,fuel connector.

    I have a Clinton chief outboard,it came with a boat that I purchased.It's way too small for the boat,but I would like to get it up and running. The engine fuel connection is totally different to other outboards,and it didn't come with a fuel pipe with the connector on it. The fuel pump is part...

    Jammed open stat on 1963 18hp fastwin.

    I have a 1963 18hp fastwin,the stat on it is jammed open,i may have to wait a while before I can get a new stat. I know running without a stat prevents getting all the two stroke oil to burn with the fuel. Would it be ok to run with a jammed open stat for a while?

The engine starts easily,and ticks over,but when I give it some gas it spits back before it increases in engine speed, runs for a few minutes,and cuts out. The carb has been cleaned,the...

    Starts first pull and ticks over no problems,if I increase the revs,it phuts and stutters,picks up and cuts out. The compressions are good,and there is a new fuel pump on it. I had the carb off and cleaned and used carb cleaner on it,set the bowl height,and the bowl cut off jet is clear and not...

    1999 25hp johnson conversion to 30hp

    Is this just a jet change in the carb,or will I need a 30hp carb of the same year? Obviously,it is pointless looking for more revs,because it will go over the WOT limit,so would this conversion give me more torque?

    I have fitted a new fuel pump,the ad was a bit vague,it turns out the pump is for the 75hp plus. It fits exactly the same as the old pump.The fuel outlet nipple to the carb on the pump is a larger dia than the one on the old pump. I changed the nipple over for the one off the old pump. My...

    Johnson J25RLEEB Ser No-G04668104. Not had the motor on the boat yet. The motor starts easily,and will tick over,but If I increase the revs and hold it there,the engine exhaust gets smokey and misfires to the point where it would cut out if I didn't come off the revs. The plugs are new.When...

    compatable cables

    I have a 1999 25hp johnson,it came with a single lever control box. The control box on my boat is a twin lever. Would the single and twin lever cables be interchangeable? I intend replacing the cables because the old ones are not really adjustable because of weather exposure and age. The single...
