The comparison in the 268 to 270 change was that the 270 was made to support the heavier 4 stroke motors. They made the hull full length to the transom instead of a stepped hull I think is how it was described on the 268. Haven't been able to compare that to see for myself.
Correct. The bottom of the 268 did not extend all the way to the back of the Eurotransom. They 270 has a full-length bottom, and a higher HP rating (500).
I would be looking for a 270 over the 268 just because I would love to have twins over single and larger rather than smaller motors.
268 can have twins, just a lower rated HP (450, I think).
I have had a boat for over 20 years that is just barely able to do 33 mph, and I can't tell you how many times I am sick of this slow speed when trying to get in before a storm, etc.
Would I be happy with a boat that can do 45mph? Likely!
Heavily loaded, with curtains up, we can do 42.
Would I be happier with one that would do 50? For sure!
You would need F225s, or more.
Would I be happy if the boat would plane on one engine in case of failure? Absolutely!
If the engines are propped properly for dual operation, then it's tough to get up on one. Might be able to with BIG engines.
So, seems that the research I have been doing over the last few years in by search for a boat (and by the way why haven't I triggered the purchase yet? College that is almost over) has been finding that 150's are light enough to allow some of the lighter boats to plane on a single whereas you need to move on up to twin 250's to get it back over the added weight.
Have heard that if you go from 150's to 200's, the performance is negligable due to weight, that the Yamaha 225 helps fix the added weight some over the 200's, but that the 250's perform nearly as well as the 150's in most categories except for trolling and idle, yet run on lower rpm's so likely the 250's are not working as hard and will last longer.
I dunno ,but if I found a 270 with twin 225 or 250's, I would jump on it hard whereas I would look around longer if it had 150's.
The F150s (or the 150HPDI) are absolutely great on the 270. The 200HPDI are even stronger.
Also, figure by the time I add fuel, water, curtains, gear, and 4 or 5 fat guys, then my former 45mph boat would now do about 40 wide open and that is too hard on the engines, so guess what, back to that 20-25mph cruise that I am not happy with. I want to cruise at 30ish. Then I feel like I am moving.
We head offshore with full fuel, full water, all the gear for trolling and deep-dropping, 200+ pounds of ice, five people who weigh the same as seven or eight, curtains, etc. We cruise at 26-28knots, and have run back in at 32kts. WOT loaded like that is 36+kts. And we get 1.6-1.7nm/gal when cruising that way.
