What hull do you have?

Splash

Hey Splash - Interested how the re-rating process works?

Does the hull get inspected by kpsmarine, or do you send through the specs?

the difference is only in top end speed, both the 50 and 60 will have same down low from my understanding

I reckon go the 60, I cant see you even noticing 4kg, thats just like parking a 6 pack on the seat beside you.

Certainly the 60 on a heavy boat like that will be a better proposition especially on the NT as you say in the fast flow you get up there...

Well there Chris the suzuki DF40 and 50 are 3 cylinder engines and the DF60 and 70 are 4 cylinder engines so I guess your information is incorrect

Your thoughts on the 3 cyl. BF60 vs 4 cyl. F60C?

Bf 60 has lean burn technology, nmea 2000 compatible. Higher charging capacity, lighter

The f60 has been around for some time and is reliable as hell but is starting to fall behind in technology

Now Spanairdking the suzuki is 941cc for 40A-50A-60A hp and all the same revs so just more fuel and air to make the hp in there case but the yamy 50 to60hp is 300rpm same ccs so more revs and id say more air and fuel to get the 10hp extra.
