    Since your boat runs a timing case driven dog clutch this raises many issues when trying to run a closed cooling system...

    An automotive pump needs to be fitted to provide circulation between the engine and heat exchanger. With a timing case driven dog clutch, there is no way of driving an automotive pump with a v-belt.... an electric pump could be adapted to fit the 308 timing cover to provide circulation. The 3/4 raw water impeller pump (for open circuit cooling) is still used but only for cooling the heat exchanger and the exhaust manifolds. A heat exchanger has its advantages when running in salt water all the time but a thermo control type open system can regulate the temp just as good and is a lot simpler.

    If the engine was around the other way, as in a dedicated marine engine, both pumps are easily driven by the harmonic balancer.

    Hey Tinman and Ski351, I stumbled across this on the net quite by accident. It's my one of my old boats....but a long time before I owned it. Hopefully the link works. Check it out
    AUSSIE SKIBOATS: the "MISTREATED" album; 'MISTREATED Ski Racing' ....(aka "SIROCCO IV")

    Nice boat . Anything with a rear mounted Ford V8 gets my vote.
    Lots of good pics and info on that website.

    yeah as I said above somewhere, I'm not after top end speed. Even 45-50mph is enough and i have about that.
    To be perfectly honest, my 4.75m Flightcraft Phantom has all the power it needs for social skiing and even a bit of hooning. It's a freshly built 308 that just needs a bit better tuning.
    For me at the moment it's not about building a race boat or anything like it. It's more about the process of learning about the engine, learning to tune it, learning to fix it and where and if possible learning to extract a few more Hp from it and a bit more torque. "Why?" you might ask. Coz it sounds like fun
    Oh, I've had a faster boat. A Skicraft Interceptor with a 351 Clevland in the back. The "Clevland Express". Went pretty hard but the guy I bought it off was a tight ass and fixed it with the cheapest of cheap. The boat was wired up with cheap crap figure 8 speaker wire. Haha! I sold it back to him. Years ago (way before I had it) it was good for 100mph+ with a worked 351c. I wish I'd had it then

    I've had a couple of nice outboards too....but I'll save that for another day
    Hi Smokin 308,
    I stumbled across your mention of a Skicraft Interceptor skiboat running a 351 Cleveland.
    This was originally my boat. In 1980 I bought it from AR Marine in Melbourne and skiraced it in under 5L class. It had a hot 302 Cleveland running 4x dual throat downdraught Webers, etc, etc. When I stopped racing I put a 351 in the back, took off the extractors, made a teak engine cover, and made it a more 'social' v-drive skiboat. You can see picks of the boat on 'aussie skiboats' under the name 'Mistreated', together with some of my other boats. I see that you are in the SW. Me too. Often skiing on the Blackwood. Send a pic of your Phantom (another classic!).

    G'day Gagman,

    I think I 'spoke' to you on that Aussie Skiboats page a while back. That boat is still in a shed in Katanning as far as I'm aware. It's a ripper of a boat but unfortunately it needs a tidy up. The guy who owned it does everything on the cheap so it suffers a bit maintenance department. Would love to buy it back one day and restore it

    Free HP (top end speed) hiding under your boat right now!

    Cool. reading your thread, did you ever power up your 308?
    I recently had mine rebuilt as follows:
    balanced, 10.5:1 pistons, Crane Powermax H264 cam (ideal for dog clutch/low idle), L34 spec heads/valves/springs, Edelbrock Performer manifold, Holley 650 double pumper spreadbore, MSD electronic ignition.
    Added a thermostat control unit for the water flow as the engine was running too cold.
    End result...lots more torque. Engine pulls way harder all the way to 4,800rpm spinning a larger 12x15 super cup prop where before it was only pulling 4,500rpm with a smaller 12x14.
    Not a race boat, but a strong midmount clinker.
