Need of some help Chrysler 55hp 1971

One problem is that most parts diagrams don't go past 74 so finding the right parts can be tricky??
Contact Franz Marine or Master Tech Marine for older parts.
Do a pressure test before you buy parts for the lower.
It might just be a bad drain plug seal??

Pics of the choke? It might just need a shot of WD
Also if the key actuates the choke, a shot of WD in the switch might help.

Ok so got the boat out on the water. 14 ft fiberglass crestliner and it only would go 11 knots . It idles fine revs up decent but I feel like it should have way more top end . What should I look into to make this thing as fast as it should go. I don't have a tach hooked up so I don't know what the rpm is . I looked at the prop other than being banged up a bit the bushing inside looks decent. Could this be a timing issue . What should the timing advance be on this boat. What else should I check to make this old thing faster

Does the motor rev up and just not move the boat?
That would be the prop's hub slipping.

Ok I have another prop I will check that

Wow Lot of great info. Proud owner of a new to me 70 Chrysler sport satellite 55go so will probably be more questions in the future

Wondering what forum I can get seat making advice as this boat is bare inside

They have a "boat repair and restorations" section.
Try there?
The mods don't like it when you ask questions on another's thread.

So I bought a new coil and it already got to hot and blew the casing of the coil. The one I bought was off eBay and 90 bucks . Resistance was 3.0 ohm primary and 8k secondary. So going off what nordin told me I bought a automotive coil that I am going to install . It says it has no internal resister and it has 1.5 ohms ohms primary resistance. After reading the internet I am concerned with running this coil. Everyone says that a 1.5 ohm coil running 12v will burn my coil and points . I don't want to ruin my points . Anyone want to chime in what I should do here?

 

[jerryjerry05]

I'm not sure but most points/condensors blow when the voltage is past 9v???
I know the coil with the internal resistor drops the voltage down to 9v.
