- Twin 5.7 V-Drive
Going through the motions of purchasing a '97 300 SunDancer. She has 604 hours on the pair-o-5.7's, v-drives.
We have a surveyor who was recommended by a lot of resources, including several posts in this forum.
Anyways, for my curiosity...I know straight inboards and v-drives loose a bit of performance from the I/O's. I know a lot of boats with a pair of 350's with bravo III's would nudge 50. And with single props would be low to mid 40's. What should the same setup on v-drives get...36 or 38 mpg? What's good rpm for WOT? I'm sure the surveyor would know just curious for myself as I eyeball the gauges on the sea trial.
Believe the tanks will have ~75 gallons. Current owner quite meticulous...does much of his own work and I've seen it, he's a carpenter that does fine woodworking for boats. Fresh bottom paint this year, just launched ~10 days ago, well scraped/sanded so the paint job is smooth not several layers crusty and peeling.
