I am pretty sure I am gonna go with a single 800-850 cfm carb looking if anyone has anything let me know

she's alive

I have a 1980 25 ft with a procharged 489 ,it had a trs that i switched over to a bravo with a 12 inch extension box.I boat in the niagara river just ahead of niagara falls ny. we get some pretty rough water here and this boat eats it up.cruise all day at 70 to 80 top at 90

i'll vouch for that dinsmore boat. it runs really good! i have 1981 31ft ss i ran in the same area til i moved 5yrs ago. i was told it was the last martini built and to settle a suit against them the name corsa came to be. my title says martini and the name on boat says corsa. still have it, although it hasn't been wet in 2yrs i'm looking forward to using it maybe in the next few weeks.

Thats a good looking Martini you have. Great hull great wave crusher...
