115 hard to start

[steverob206]

I have 1982 merc. 115 inline 6. The first time to start it takes about ten mins. Then when you hold the starter engaged for five or six seconds it starts to fire and come to life. When you go to full throttle for the first time it takes a minute of two to build up rpms. Then will advance to full throttle 5800 rpms and 52 miles per hour. The rest of the time on the water that day or weekend it starts great and runs fine just that initial startup is the problem.
I took it to the dealer he said I needed a carb job plus both switch boxes. About ten years ago it did kind of the same thing at full throttle would only run 2500 rpms. The dealer replaced one switch box and the problem continued. So, he put my old switch box back on and replaced stator coil. Could the coil be making the engine hard to start?

Re: 115 hard to start

run an ohm's test on the stator, same with coils. does it only act like that in the water? have you tried manualy pushing the throttle arm open while trying to start it. how about pumping the bulb on the fuel line?

I don't think I have any fuel problems the bulb seems to be fine.

It may not be a fuel problem. Do you have good spark and compression on all ctlinders?

Re: 115 hard to start

in line are gas hungry at start. this is how i start mine and it works everytime. pump bulb till hard, idle lever all the way up, hold choke, turn engine over 5 or 6 times, then repump till especially hard, hold choke, and start. i have to play with the choke until the engine settles down, lower idle lever partially, and starts to warm up. it is just the nature of the inline beast.
