Hi
I just became a member of this great powerboating community, and thought I'd share my project with you guys hoping to get some feedback in the form of advices, opinions or anything else :)
The boat is an old Hurricane 470 16ft speedboat with a deep V-bottom. I got it very cheap from a guy who had it in his garden leaning up against a hedge for years. The boat was totally stripped and the bottom was scraped clean of about 40 layers of old antifouling.
Some pictures of it:

I first bought a 1984 Johnson 70hp which turned out to be totally blown. Ended up selling it in parts for the same price I bought it for.
Then I bought a 1986 Evinrude 120hp looper. It had been stored in an old OMC workshop for years, but it seemed to be in a relatively good shape for the price.

But when I took a compression test, only one cylinder had good results, bottom starboard side had poor results, and the two port side cylinders had no compression at all. Started tearing it apart and found out that it needs a total rebuild and new oversize pistons. The port side headgasket was completely torn apart between the cylinders, and the bottom port cylinder and piston is really "worn out". Fortunately the price was very good so I can always sell it as parts and get back what I paid and even more. I have not decided what to do with it yet:rolleyes:
Couple of pics of the damages:

The guy I bought the 120hp from, had a 1982 Evinrude 90hp that he said I could buy for half the price of the 120hp, so I took a chance on that after finding out about the issues with the 120hp.
This 90hp was stored in an outside storage for god knows how many years, and the guy I bought it from did not know the condition of it at all, but he allowed me to take a compression test before we sealed the deal, and the results were good with around 125 psi on all cylinders.

Tried starting it, but found out that it had a gas leak between the fuel pump and fuel manifold, so I replaced a hose and the fuel filter gasket and the motor started right away:D So this is the motor I will be running on this boat for now.
A video of the second startup:

Based on what other people say, I should be expecting around 60mph with this motor properly rigged on the boat.
I just bought a used CMC power-lift from Stoker2001 (thanks for that:)) that I will use on this boat.
This is my first powerboat project and I am very excited to see how it will run=) I'm thankful for all advices and opinions I can get from you!=)
Will update here when I get things done with the boat.
