I saw you mentioned that repower in your future but you were going to use the current ones for a season or so. If they check out ok and are running good why not and it will give you a chance to work on other stuff and evaluate everything including performance power wise as is currently. If I were to repower I would be looking at those Suzzuki's also. I do like the Yamaha 4.2's as well. They would be the only 2 on my list. I'd love to put the Yam 300 on my 2120. As would be only a single and I'm playing around with adding an inverter to run my AC underway for periods of time, the Yam has a 70A output vs 55A and its 44lbs lighter. As you know on the 2120's the weight is an issue and if I go inverter I will also have to put at least a 100HR house bat in my port jump or in the bilge. I'll need to cut all the weight I can. In the end though, the engine itself trumps those 2 considerations. I've been very impressed with the Suzzuki's on the boats I've been on with them. Did a charter a few years ago and the guy had 3,500 hrs on his Suz 250 and it ran like a top. Looking forward to seeing your projects. I'm just a little jealous
