hi Randyw,
i dont know,ill try and get hold of my unit builder and ask him the pich of impallas and clearance of statter housing,
i would say it is set for 350 hp,as thats what i asked for,i got the nosel back off him when he rebuilt it. at 95 mls, but ive takin it down to 92 mls to get some more load/speed because the rpm range has changed form the 302 chev to the chev 400 s/b.
i did try it with the 4oo a month ago with the nosel at 88mls but it wouldent put any higher that 4100 rpm with the 600 v/s on it,
so now ive set it at 92mls nosel and fitted the 750 d/p ,and tryed removing a little more weight out of the boat.its a ali craft,16 ft mono hull,2 seated.
it did have a 265 hemi six with side draft delortos (48s) and worked like a e49 motor about 300 hp.,
it did 115 kms on the water,
