Re: Bow heavy Starcraft...how can I remedy this?

Ya maybe Hooty, I run my motor with the cavitation plate 4 inches above keel, I have a prop that can handle the loose water.<br /><br />Of course this is only a "guess-along" but from what I have heard so far, I dont see why a high quality, high rake prop, will not help the situation alot.<br /><br />Is the boat design so poor that it cant be helped? Ya wont know till ya try, borrow a test prop from a dealer.<br /><br />If the prop gets you close, throw a little ballast in the stern. (Allular) I would not add ballast first, as this is a last resort only.<br /><br />One more thing, if at all possible, move the heavy stuff as far back as you can. Against the transom if possible. Later, Mike

Re: Bow heavy Starcraft...how can I remedy this?

Hello again. So I could run the same size prop with more cup and perhaps get a fix for the trim? I'm running in the ideal rpm range with the current prop setup. All the heavy stuff is in the rear of the boat. The only thing left to move would be the seats so I've done all I can do there. The last time we put put the shop tach on it with only two of us on board, six gallons of fuel, two batteries and without the current lounge seats I ran 5500-5400 rpm at 46 to close to 50 mph. <br /><br />Here's a pick before I fixed her up. <br /><br />

Nice boat Allular, it would be nice to see a pic of the stern also. I think you need to try a high rake prop.

Looks like you have enough ideas to try to <br />fix your bow heavy problem. But if you can get a message to Star Chief 24, tell him to try oldboatlit.com for manuals, brochures etc.

Doel fins solved my bow down problems very well. This product also gave me a greater control over the ride position of my boat and created better skipper - crew compatability as we didn't have to move around to level the boat. I can't recommend it enough!<br />Ross

Re: Bow heavy Starcraft...how can I remedy this?

Allular - <br /><br />Your boat looks very similar to my '76. I'm running a 70HP Evinrude & I'm playing the propeller game come the spring (once I finish rebuilding my transom). In my minimal experience and non-existent training, I think you're doing just fine:<br /><br />

The last time we put put the shop tach on it with only two of us on board, six gallons of fuel, two batteries and without the current lounge seats I ran 5500-5400 rpm at 46 to close to 50 mph

With just me in the boat, 1 battery, 18 gallons of fuel, and the kicker motor & a spare 5-gal under the foredeck, I just tickled 30MPH with a badly banged-up 13 3/4X15 prop @ around 4500RPM.<br /><br />I put a set of DoelFins on mine, and the boat just goes on plane with MAYBE 2-3 inches of bowrise. I'm just thinking that the perception of bow-heaviness may simply be the nature of the beast. <br /><br />It was kinda weird the first couple times I was out in my boat, because I was used to my friend's 16' Whaler, which had the helm about midships instead of forward, and would lift the bow about 2 feet before going on plane. Completely different feeling to get used to, but I find I like it.<br /><br /><br />Good luck!

Re: Bow heavy Starcraft...how can I remedy this?

kilroy, look at the post date....were 4 years late....BUT,<br />

Your motor is mounted to high, you should be able to trim all the way out without sucking air,

This is exactly BACKWARDS....if you can trim all the way, the engine is TOO LOW!<br />The SST is a stern-lifter...we need a Turbo1 or a Raker for this, and THEN we need to lift the engine...<br />By the way, 5400RPM is 400 short of where you should be, the gear ratio is 2:1, and a 17 won't push'er that fast...

Kenny <br /><br />I just recently noticed the breakdown by manufacturer. I guess I got used to looking at posts the "100 days" format... Figgered if it was on the first page , it was current. I never looked at post dates before.<br /><br />oops...<br /><br /><br />Hope you had a good Thanksgiving!<br /><br />Matt
