i will be working on all the suggestions wrt my will not start problem starting with installing the new starter when i get it. will let you all know what happens with compression tests and reeds. thanks again
i removed the failed starter and disassembled it. it was dirty but no obvious damage. on reassembly and install on motor, it was able to crank the motor fast only if i took out the spark plugs. with spark plugs it was able to turn maybe one half rotation, hitting compression i guess. the starter...
thank you all for the responses. i did the things you guys suggested to the best of my ability before i took the boat to the two repair shops. also removed and cleaned carbs. but it still showed no life at all. the failure of the two shops to tell me what the problem was at least surprised...

after having spent hours on the web looking for a starter for my 1973 chrysler 70hp 3 cylinder, it seems that only one may fit and it costs $245 plus shipping. since i may have even more problems with the motor(two repair shops failed to fixit and burned out the original starter in the...
hi guys,
my 1973 chrysler 70hp 3cylinder outboard has been running great for 4 years now but i want to use it more as a trolling speed motor than full power running. so my question is: am i harming the motor by running it at just 900 rpm? what kind of spark plugs should i be using to...
steering wheel won't turn. disconnected motor universal bolt from steering cable and motor turns freely. unscrewed big nut on cable at steering wheel rack and pinion and rack moved freely. so, i guess the steering cable is frozen inside its sheath. to replace the cable, i have to get the the...
my steering wheel cracked at the hub. about a 3 inch long crack. still working but i'm afraid it might completely let go. so my question is what holds the steering wheel to the shaft? is it a tapered shaft? a splined shaft? big nut? is it hard to get off like a car steering wheel?
hello,

update on 1973 chrysler 70 hp engine problems
well, it's running great now.
the end play of the prop shaft was actually about .015" after replacing the rear bearing carrier. and after reading frank's letter i decided that...
after replacing the rear propshaft bearing race carrier in my lower unit, i found that the propshaft went in and out about .062".
the tapered roller bearings at each end of the shaft which sit in the respective races determine the propshaft location in the case and therefore the...
hello,
i need the ring or collar that you see just behind the prop that has two allen head bolts holding it to the lower unit.
i don't know what you call it.
this past winter it cracked right around the lower allen head bolt. i don't know why it did. i emptied the lower unit of all...
my 1974 chrysler 70hp 3 cylinder starts easy but runs only about 30 seconds and dies. if i turn the ignition off, it will restart easy and again run for 30 seconds and die. i can repeat this test forever.
the confusing part of this test is that if i just turn the ignition switch to...
