Hi!
I had a Rana 16 Line, but I bought an Alicraft 18 Norwind a few weeks ago, and the same Mariner 90HP 2T (From 2001) will be pushing the boat.
I want an aluminium prop due to lower prices.
The Alicraft is 5,65m long, 2,30m beam, 500KG dry-weight without people, gas, engine etc. This is the official numbers from the brochure that I found (It was from the 70s, a picture is added, but it's on Norwegian, but you can see the names and numbers).
The hull seems to be good, some said that it's a 24 degree hull, could that be correct?
A few pictures, not my boat. The hull on the inboard and outboard is excatly the same.
I've been looking at a 15P Spitfire prop from Quicksilver, I have not tested the engine, RPM etc. as the boat is still 3 hours away, and the engine is in my garden.
I reckon the top speed is between 33 and 36 knots based on others (30-32 with a 70-75 HP 2T, 33 with an F80 first gen).
I want to have the best economical speed, top speed is not important, will never run it on WOT. I do fish/troll, so the three "speeds" I will be using is either 1-3 knots, 5-8 knots or 23-26 knots. Trolling, calm cruising or my go to speed for hurrying.
This is why I really want a four-blade prop.
Thanks!
Important notes for engine: Max recommended RPM is between 5000-5500, 2,33 gear ratio, 90HP two-stroke
