wanted some opinion on the steps I should take to fix this boat right.
So I bought a 1997 challenger 1800 under these presumptions:
-5 months ago it had the left engine replaced with a rebuilt and bored engine but wasn’t tuned or adjusted
-5 months ago all of the carbs were rebuilt
-It hasn’t seen water in 2 years
-There is water leaking into hull unknown source
-New battery
-new wiring harness
-few other minor issues
so i started it up out of water and I noticed some flow issues for the left engine fresh water outlet there was water coming out from under the ski rope hook at fairly high speed.
left engine runs and idles well at 3k rpm
Right engine idles at 1.5k rpm took a bit to get it idleing
next I took it to the water right engine holds idle at about 1200rpm. But is sputters and won’t go over 3.5k rpm feels like a rev limit. Left engine won’t idle it just diesbut it purrs like a kitten when I rev it and goes to 7k rpm.
Verified all the hull leaks are coming from loose bulkhead fittings and a bilge hose. I also have go get a new fuel sending unit float to fix the fuel gauge.
so to fix the engines this is my preposed tactic.
-First I have no idea how old the fuel and oil or what type are in each tank. So I plan on draining both and replacing all hoses.
-Next check compression on both engines.
-Next replace fuel and oil filters.
-waiting on shop book so I can properly tune and adjust idles and chokes for engines.
-clean out internal carb fuel filters
-Clean all rave valves.
-check to ensure each engine is getting oil.
-check exhaust hoses for blistering.
-replace all bilge hoses
-also the left engine throttle just falls it has no resistance and I can’t find the resistance screw to change that.
So that’s the plan as of now if anyone has any other ideas let me know. Thanks I will post once I get each thing done and if it changes anything.
