1988 johnson 48 special

Hi , this is my first time using this site so forgive me if I make mistakes. so it is hard to turn over with plus in. turns over fine with plugs out. I put 1 plug in and starts and runs on 1 cylinder. I switch cylinders and it starts up again. Any ideas? Tnx in advance

the starter needs to overcome compression and that requires all the volts/amps available from good and charged up battery.

first thing to do is clean all connections to/from the battery, inpect all crimps for oxydation .

clean all starter & solenoid connections shiny clean

the starter itself may be aging (weak) but do simple stuff first.

the engine runs on either cyl. so things are not all bad ! is this a new to you engine ?? is this s new/sudden issue that came up ?

Thanks for the quick reply ,I'll will check all connections and let you know

Inspect lower unit oil.-----For this issue I would charge the battery and have it load tested.-----Then take starter apart for inspection and ohm check on armature.-----Costs no beer tokens to take these steps!

Hi, I bought the boat about 6 months ago, I have redone the whole boat( a 1972 lucraft) it came with this motor. when I first bought it I tried starting it up for 5 sec. so I knew it ran. Now I changed the lower unit oil ,installed new water pump and now have this problem. I have not had a chance to do what crosbyman suggested yet but I will get to it soon. tnx for your reply, do you know what the armature should ohm out as?

Should show infinity from commutator to ground.----Digital meter.

Tnx I won't be able to test until Thursday (out of town) I will let you know then

Tim... not saying the starter is faulty or not & it is up to you but personally I would do the easy stuff... clean all contact points before openning up the starter .... progress from easy to more complicated stuff (relatively speaking) .

On a 34 year old motor I take starters apart for inspection.----Nothing to them.----Very easy.

Thank you for your instructions, I cleaned every connection I could find. I changed out 2 wires (they were cracked and old) , replaced several connector ends and it starts right up! Thanks again Tim

tim, thanks for your feedback. I am glad that is all it was.

just feed that oldy good fuel and oil , check the gearcase oil has suggested . Always use new nylon washers on the GC and always check- drain and refill before freeze up.

Will do! Tnx again
