Valiant 450

Hi all
Im new to this game.
Recently purchased a 2004 valiant 450 +50hp mercury 2 stroke. Both appear to be in very good condition.
Always my ambition to own a rib for cruising in shore. Anybody got any views on this boat and engine. Have gone out a couple of times but being very careful until I get used to the boat. Any ideas on fuel consumption and reliability of this package.

cheers

Hi Gerry, welcome to RIBnet.

That should be a well matched combo. Two Stroke Mick in Castlebar runs a slightly bigger version and speaks well of it, but he's not Merc powered. Have a nosy round the forum and use the search facility. I'd guess about 0.6L/Nm if you don't plant her.

There's a lot of very useful information on here,

...and then there's mine

Thanks Willk.

Tried it a few times in the last two weeks its going well. rises quiet high in the front before it planes, and can be a bit worrying at times.
Prob should put a bit of weight on fromt

Cheers

Hi Gerry

Make sure your engine is well trimmed in. I also have a substantial amount of lead in the anchor locker .

Thanks for that Mick
What sort of weight (amount) are you talking about? How would a couple of sandbags work. Is trimming about trial and error before you get it right.

Cheers

Keep the engine fully trimmed in untill you are on the plane. Then trim out the engine slowly untill the steering become light. If in a head sea keep the engine trimmed in. if in a following sea keep the engine trimmed out. I am of the opinion that these boats excel in a following sea

I have approx 35 kg of lead in the bow locker. the preasone for the lead is to give the boat more forward momentum when in a head sea not to keep the bow down when getting off the plane.

Thanks mick.
Because of our bad summer i didnt have a chance to try it yet. I have got bout 20kgs of lead ready to put into the bow storage space. Il play around with weight after that for the best result.
Trial and error I spose.

thanks

Dole fins will help get it sitting more even too without adding the weight and it will make a saving on fuel too

Worth a consideration ?

This made a huge positive difference to mine and with the added benefit of not having to drill the anti-cav plate.
