johnson 70hp 1995ish

[dmoriarty51]

hi folks i have a what is supposed to be a 70hp johnson hanging on my 95 crestliner 1650 pro am sc, it has a remote oil tank in the boat tilt and trim, and is remote controlled at the console.

i need the year, model number, and serial number of the engine to get my insurance to cover the rig for liability and cash value. not to mention getting parts and such in the future

problem is i cant find a tag on this motor anywhere. a previous owner decided to paint the hood of the motor black overtop the decals and all so any clues that may have been there are gone.

i read a bit here and found the silver freeze plug in the head with G 3873300 stamped on it. i realize this assumes the power head has never been rebuilt/replaced

on the block i found a date code of 3/94 and a casting number of 336343 d3

can anyone confirm the hp and year of this thing? or tell me where i should be finding an id tag of some kind?

also what should be on here for a prop? its currently a 13 3/8 x 17 #389948 stamped on it, but its kinda rough so im thinking of a new or repair and want to weigh my options


i had some problems last time out with it dying at cruise speed once and then had some idle issues afterwards. prior to that it seemed to run ok. after getting it back home i pulled plugs and they are toast, checked compression and found 125-135 on all cylinders

i plan to replace the plugs fuel filter, and drain the fuel tank due to unknown age and origin.. sounded like the rig had sat a while before i got it 2 weeks ago through a winter at least being im in iowa

sorry for the poor punctuation on this book just need to be pointed the right way here

one more bump, i realize there are alot of questions in this one post. im mostly concerned with learning the model of this motor and if that is indeed a serial number for the motor that i located on the freeze plug

What other numbers do you have on the thing?

The prop was used in 1979-2001. not much help there.

There should be a tag on the port side of the transom clamp with model number and serial number, there is on all the OMC motors I've seen from mid 70's to my 1990. Stand behind the boat and look on the left side where the motor swings left and right to steer. If you can find that put all the information from it on here.

I think there is a freeze plug type thingy in the top of the power head with all of the same information, there was one of these on a mid 80's 70 I recently parted out. I'm pretty sure it was in the same vicinity as the steel loop for lifting the motor.

Post a couple of pictures and 9 guys will tell you what it is in 10 minutes.
