Tested | Haines Signature 788 with 400 V10 Mercury 4-stroke 

Very interesting! I've got twin 225HP V6 Mercs on my 788SF and my fuel usage is slightly better than that at cruising speed (50km/h, ~1.35km/L) but slightly less at WOT (0.6-ish km/L) but a bit quicker too, +93km/h. I was thinking that the 450HP Racing might be the way to go... Be nice to see one of those on the back. TBH, I was expecting better out of the V10 400HP.

Nice boat, but probably a 300k trailer boat, boating has gotten way too expensive unfortunately

No good for offshore fishing in tassie just a show pony
