Why 4-stroke? I've got a 60hp four-stroke as my main power, but decided to go with a yamaha 4hp 2-stroke as auxiliary because:
1) it's lighter on the transom
2) being a simpler beast, it's more...

Porpoises, dolphins, sharks...

...apparently there are even whales off Anglesea:

Hit at 40 knots, I bet the whale had some headache afterwards.

I agree I only gave it a quick glance. But the boat had shipped (figures adapted for convenience) 240 litres in 48 hours. That's 5 litres an hour, average. When it's coming out again, it's got a...

Even when mine was carrying a quarter of a ton of water in the hull, on the trailer on a slip, nothing came out until I unscrewed the bung!

Might be worth trying the hull drain. The o-ring on mine looked a bit cracked but screwed in tight, making it hard to believe it was the source of such a big leak. But it was!

The lower of the two drains (i.e. the hull drain) on the Valiant is threaded just like yours. The Valiant's deck drain is the one with the expanding bung.

Good to hear you got sorted, sounds like...

The new hull drain fitting and bung seems to have sorted my leak. Had the boat on the water all day yesterday and barely a drop got in. Next step would have been the deck drain as per Ian's comments,...

A 3/4" hole in the deck can hardly do much harm, so sounds good from a structural point of view. The only drawback I can think of is the design involves a permanent spigot rather than a flush...

Ian, you're not saying that the anchor locker was the problem all along, are you?

I've no doubt you're right that it opens directly to the hull void, but it's got a relatively tiny catchment...

Congrats on the detective work, Ian!

And thanks. It would appear to match my leak pattern too. I'll try take a look tomorrow. Unfortunately I think I'll have to take the transom lock and/or the...

Hi Ez!



I take your point about cutting holes in the hull, and about how useless a pump would be if you got a really big leak. And as you say, the tubes should always keep you afloat.

The friend's one-way flap is on his hull drain, can you use an expanding plug on a hull drain?

I don't fancy putting my head in the water next to the prop trying to plug the hull drain after it...

A friend of mine has something like that to suck water out of the hull when planing. Problem is it lets water in when the boat's at rest :(

My front locker's always got water in it, but that doesn't mean it's not where water gets into the hull. Must take a look.

Ian, when you say you filled "the inside of your boat" do you mean the deck or the hull void underneath? I think you mean the deck, but if so, then an eggcup-full is practically nothing. If I had...

Here in Ireland, you have to be over 16 to drive a boat capable of over 17 knots. We're more regulated than you guys :eek:

Of course, enforcement is another issue entirely ;)

It's a good thought!

It would certainly solve the problem if leaks were an ongoing irritation.

The most likely difficulty I can see is making sure that the foam gets into all the crevices of...

Mine's a V490 too but I suspect it's a different model. 1999?

There's a deck sump at the aft end of the deck with a central hole in it. It doesn't give any access to the hull void, it just leads...

Hi Ian!

Interesting. I'm replacing the lower threaded bung and socket tomorrow in hopes it will help. Sounds like it may not cure it. I'll keep you posted.

OTOH it's possible the pressure...

Thanks for the helpful advice, guys. I'm going to replace the hull drain fitting, socket, bung, the lot and see if that cuts down the water ingress.

If it doesn't I think I'll put a 50mm hole...
