'73 Chrysler 105

[Baitwasher]

Hey , Brand new to the forum as a contributor, but a long time reader, Need some opinions here. Looking at doing a trade for my old '70 Evinrude 40 hp complete controls and all, just did a tone of work on it and it runs sweet- Looking at this '73 Chrysler 105, the fellow say's compression is between 50 and 52lbs on all 4 cyl. I know that the important thing is that they are within 5 lbs. of each other.. but don't ya think 50 lbs. is mighty low ?? The guy hasn't run her in 'bout two years,, ya think it may get a better reading if he tossed 'er in a can of water and got it up to operating temp then test compression ? Also he says he has no controls for it and I've searched around trying to find something and not having much luck. My boat is a 16' got any clues for me here... never messed w/a Chrysler Don't know if I should, but would like extra power.

50 lbs is LOW. my 105 has 125 ish across all 4 cyl.

Re: '73 Chrysler 105

Guages, technique and conditions vary too much to call 50psi low, particularly given that she hasn't run in years and all four are very close.

If you are seriously interested (I would not be) do a test correctly with a known good guage.

That is academic. 105HP is almost surely too much for your 16' boat and you might look for years without coming up with controls, etc.

The 105 is a good motor but, the issue of controls might be a problem. Check on ebay and other sites before you do any swapping. My two cents worth. MOPARMAN

I'd run from the 105. Not only is the control box an issue, but they haven't made ignition parts for it in decades, etc.
