Just curious why you didnt consider a 23 M220 as there are lots left over from last year at a good deal. Regardless what you pick Id get an M6 minimum and if you find an LT4 I'd go bigger. Ive never heard anyone every complain and say they wish they would have gotten a smaller engine.

Oddly enough my local sent me an M220 and the price is intriguing.  I hadn't considered it originally given the sky high list prices and the lack of any additional space.  I will probably go test drive it soon.

Hey everyone, I’ve been looking at this forum for a long time but this is my first post! Just finally made it out this season today and the boat did a few things it’s never done to me before. I will say I did wash this morning and did run on a fake lake. Right after getting it into the water the boat felt like it was vibrating a bit. I have a slightly chipped prop on my 92 pro star and the vibration was similar but it wasnt the same feeling. Got out of everyone’s way to put the Bimini up and was waiting for my friend to walk down the ramp after parking the truck and had an engine temp threshold alarm. I shut everything down waited about 30 seconds and restarted the boat. Revved it a little and watched the temp drop. After this I eased the boat up to around 30-35mph. Rode like that a ways with a few no wake zones in between. Gauges checked good the whole time. Got to a place we normally swim and all and shut it down for a bit. Well I was easing around about 6-7 mph talking to a friend about going to pick her up from a different ramp when a surf boat wave came over the front end of my boat. Not an extreme amount but enough to get the floor wet. Traveling this same speed I was holding at the boat felt like it started vibrating slightly so I stopped. Auto bilge kicked on when the boat leveled out. Got all the water out and went towards the ramp with no issues Except the vibration which seemed like did change at the same rpm from time to time but couldn’t be felt in higher rpm’s. Pulled through a no wake zone and the boat just slam dies on the other side. I crank it back up and try to give it some gas it kicks in and out of gear 2 or 3 times and dies. I crank it in neutral and give it a few good revs knock in gear and I’m rolling get up to about 40 and it falls flat on its face then it caught up back to rpm. Did this a few more times headed back to the trailer and as I got closer it got better in higher rpm’s. Putting it on the trailer was an experience to say the least. It would either die or almost die and over rev kicking me to 4.5/5mph so I broke out the ol paddle 😭 if anyone has any insight into things I can try please let me know. I’m planning to do the ignition system this week and will check the fuel for water. 

Put some noids on the injectors to see if they are actually firing.  Can get them at harbor freight.  Also check timing.  Should be able to do that even if not running.  10 deg.  

Could the fuel be contaminated? 

Spark at the plug and fuel should fire. Hm. Is it trying to fire up? Sputtering/back-firing or anything ?
