Burty maybe its got to do with going to a 15" mid, When I changed on my p18 it certainly fecked the handling up .

Burty · 02-05-2006, 09:25 AM

Nah dont think so dude, i think i know why but dont really want to prove or dis prove my theory. I've just decided that 75mph is plenty fast enough

I navigated in an 18 with a 15" XR2 on, and it made the centre of gravity lower - worked a treat - that boat ran mid 80's with an old EFI on (260hp) no problem.

I think it's more props than anything, but I'm only familiar with 18's!

What Rob is failing to mention here is that that bottom of the boat was full of water as there was a small hole in the hull (8mm)

This would of had an effect on the handling as the boat landed on one side.

It's also worth mentioning that the prop has been reworked so a direct comparision cannot be made to the handling or power of the old engine / set-up.

75mph is pleanty fast enough

Not for F2 and certainly not for River trent.

Burty, is there a reason why this threads in talking bollix?

I can state from personal experience, that water in the bilge will indeed turn a slight lateral shift into a full on hook! It acts like a slide hammer, slopping across and hitting the inner topsides, and kerbam.

Just a few gallons would do it, how much was in the bilge?.....and why the 8mm hole?

Cyco · 02-05-2006, 12:21 PM

From what Rob said there was more water in the hull than there was in the bow tank when he drained it.

Not sure why the 8mm hole, it was under where the trim pump was mounted (which came loose on a previous run) ???

the hole isn't as big as 8mm prolly 4mm but didn't notice till i backed off and the water came gushing forward and over my feet. so it was full upto the lower floor which is loads.
don't know where the hole came from but its almost like its been drilled. It must of happened on that outing as i always take the bung out and no water has come out before.

You say that but I had 15 to 20 gallons (of fuel not water

) sloshing around in my fuel tank directly above were Burty's water would have been and it didn't cause me any noticable handling problems. I'm pretty certain I haven't got a longitudinal baffel in my tank either.

The floor is fairly close to the bottom of the hull at that point so there wouldnt be much room for gallons of water to slop across and hit the upsides. If there was alot of water on board at that time it would have been above floor level where there is no inner topsides to hit. Burty was sat displacing for a fair amount of time after his hook and only noticed the water on his way back in.

My opinion is 80+mph with the engine too high and trimmed out to much for those sea conditions. When it landed the prop probably paddle wheeled the back round a bit and the full bow tank made the nose land heavily and dig in which turned a small amount of yaw into a sharp (for 80mph) turn.

To be fair, if it had been me, at that speed, I would have been sat 'displacing' for quite a while too!
