1. Which will have better resale value (300 vs 350)
2. And if money is not the issue ... which would you get.

Both will have good resale. But I'll ask you. If you were looking for the same boat on the used boat market and you saw both which one would you go to look at first?

Go 350.

Along with BBP and others, I can't believe they even offer a 240 in that boat. I looked at a Sea-Ray 230lx and was floored that standard power was a 250 V6 on an almost 5000 lb boat!

But the CS23 is less than 4,000 pounds.

Well, I went with the 350. Just cause.

Thanks everyone!

A venerable motor TC. Thanks for the update.

There is also a downside to direct injection. The intake valves don't have the fuel flowing over them which keeps them clean. That is why Toyota and Ford actually have a hybrid system of direct injection and port injection on their engines.

This was a huge huge problem in the beginning. It was all manufactures. Yes they are getting it figured out. But in marine life it won't be. Just saying. But we don't use a Marine engine like a car engine. That's another reason I use BG MOA and other products from them. It helps a ton. We will see sticking rings also and oil consumption shows its ugly face. Just watch. Marine is always a few years behind the auto industry.

Did you go with volvo or merc? 6.2 vs 5.3? Di vs Fi?

Congrats! Great choice. Either way you will enjoy it. At least now you won't say to yourself I wonder what this would be like with that other engine!

Ah another magazine/internet regurgitator with zero real world experience. Ive tore down a truck load of old school gas engines that have your "fuel valve cleaner" either injection or carb, that 90% of the intake valves had substantial carbon deposits. Ive also never seen a discernable amount to even color an intake valve of a diesel.

When i get 5,000 hours on my boat about the time this would become an actual problem I give you a call.

Best write up you can find on the CS22, which is 1’4” shorter version of the CS23
