1986 chaparral 235xlc w/5.7 mag engine. Was out on water today all day, engine running good no problems. Had a skier go down on a boat ahead of me and another boat nearby make for a tight passage in between so I cut back on throttle and make a pass between the skier and pontoon boat close by. After making a safe pass and in the clear to open up throttle again had a loud pop almost like backfire type noise when I gave it gas then a loud ticking from engine even at idle. Have a 20hp kicker on back so shut her down and trolled back to dock. When back at dock tried staring her up again, and she did but tick is still there. Any help on what this may be? I'm trying to be as descriptive as possible, and will try to upload a vid if possible of sound to help.
Here is a little info on the boat since I got it in April. Had some old gas I siphoned as much as possible out(all but maybe the last 1/2 gal. Or so). Put 20+ gal. Of fresh gas in it, from the 3 times we've had it out this year and ran 2 bottles of seafoam through it. I've been having to dump fuel/water separator several time as well as putting a new one on. Changed spark plugs and cleaned carb with carb cleaner( just spray, did not actually "boil" carb seemed to be running OK with just some spray) have had a bit of water in the fuel thus the reason for the frequent dumps and change of filter. Please any help would be appreciated, I guess I should mention oil level is good and i didn't lose any after the pop. Oil pressure was also OK under load and so was temp.
I'm just praying I didn't throw a rod or something, please help
