    1971 StarCraft holiday

    Hi guys, I have a 1971 StarCraft holiday with an inboard 153 ci 2.5 L 120 HP mercruiser. I’ve fully restored the whole interior and I’ve fully rebuilt the motor. (Has been a never ending project). I’ve finally got the boat to back to being reliable. I’m from Canada and I took the boat out to go...

    120 HP mercruiser 153 ci 2.5 L issues

    Ya I know. Think it’s a good idea to get rid of the points and condenser with electronic ?

    120 HP mercruiser 153 ci 2.5 L issues

    Okay ya maybe I’ll buy a new one. We had a bunch of old ones and the one we put in fixed the problem in the driveway and the boat ran great till I got it on the water under load.

    120 HP mercruiser 153 ci 2.5 L issues

    Ya I ran it on a new tank. The fuel lines are all new as well. I thought it can’t be the timing because when it runs it runs smooth. I figured it had to be an issue with the spark due to the fact that it cuts out randomly completely. I thought maybe it would bog if it wasn’t getting enough fuel...

    120 HP mercruiser 153 ci 2.5 L issues

    Hey guys. So turns out the condenser on the distributor was no good and the wire running to the coil wasn’t giving enough voltage. Got it out on the water and it ran great now having issues again. Running full speed and all of a sudden it will pretty much shut off or other times sputter quite a...

    Okay sounds good thanks. So now back to my drain line from the fuel pump to my carb. Where exactly on the carb would it go?

    120 HP mercruiser 153 ci 2.5 L issues

    Okay thanks for your help. I took off the old carb and got this new one because of all the other issues including the distributor but now that it is in good shape maybe I’ll go back to the old carb with automatic choke.

    Now I don’t know too much about this stuff. If the carb is giving too much fuel if I put smaller jets in would that work? Also would would it cause it to operate poorly after running good for a 5 minute run.

    120 HP mercruiser 153 ci 2.5 L issues

    Okay now what would cause excessive fuel? Maybe just the new carburator I bought off Amazon is junk?

    120 HP mercruiser 153 ci 2.5 L issues

    I did drain the fuel tank 2 months ago and put all new fuel in. And yes set the timing and dwell. In order for it to run I have to advance it to the point where it sounds clunky when starting. And yes we have adjusted the mixtures on the carbs. Spark plugs are quite black so thought there was a...

    120 HP mercruiser 153 ci 2.5 L issues

    Okay thank you for the input. So I need to run a fuel line from the fuel pump I have blocked off to the carburator or back to the gas tank? I guess my next point of attack is to buy a rebuilt original carb and see if that fixes the issues I’m having? For the hose breather is it okay the way I...

    Also I’m not sure what to do with the house coming out of the valve cover. It leaks a tiny bit of oil so I don’t want to hook it up to the carburator
