Considering a 1978 F30 with a single-engine.
Are hulls of boats of this vintage solid glass or glass over wood?

Trojan lists the draft as 25" . Likely repowered . The 7. 4 Crusader is a good enginerockb1 wrote: ↑Sun Dec 27, 2020 8:48 amAdd says 7.4 crusader.prowlersfish wrote: ↑Sat Dec 26, 2020 11:43 pm Is it powered by a 255 hp Merc or 330hp Chrysler ? Or something else ?
Thank you. I would think that the published figures would be for the twins since there were so many of them and that the single would be more since the shaft is coming out at the center line and I would expect it would be swinging a larger prop.prowlersfish wrote: ↑Sun Dec 27, 2020 10:34 amTrojan lists the draft as 25" .

Did some research . Not much difference in the draft of the twins vs. the single . Why ? First there is very little dead rise at the back , not flat but close . Prop size is the same 14" as it is also 1 to 1 gear . A single big block weighs less the 2 small blocks so the hull would sit a little higher , so it all balance out .rockb1 wrote: ↑Sun Dec 27, 2020 11:42 amThank you.prowlersfish wrote: ↑Sun Dec 27, 2020 10:46 am The info I gave is what is listed for the single engine F30 .
