SR4 "bung the holes"

[wolfie]

hi, slight problem, used the SR4 last week, sits very deep in the water, so much so that it gives my engine serious back pressure problems, so many options, easiest i think is to bung the holes up, how much more flotation will i gain? current water level is only about 5 inches below top of transom, will it really get unstable at rest with them bunged up ? and whats the best method you know of ? thinking here that "patches" silca flexed in place with a few screws round,

regards in advance

TBH - that sounds like one of the worst ways you could do it! On my SR the previous owner had milled down a heavy duty plastic plug/fitting so it was a near interferance fit and then Sikaflexed that into the transom hole with a drain plug installed in the middle - easy to fit, flush and most importantly easily reversable. The front holes are easy to plug with off the shelf expanding bungs of the correct size.

Measure the hole and go to your local plumbing trade specialist to find suitable fittings.

Have a search too as there are quite a few previous topics and how-to's on this.

I have just finished blocking my SR4 off, as my wife & kids where finding it a pain keeping to speed limits as the water would drain out so throttle back hull would fill & so on! + water skiing for me was a big no no, so I'm hopping with out the hull full of water I may stand a chance of getting up! Or I go on a crash diet!!!

MAX - obviously i did not mean just some rough cut plate screwed on, but like in one the links you posted, round SS plate etc, so has some one who has bunged up the holes worked out how much free board i would get on the transom ?

Rubber bung in the bow and a tennis ball in the transom

Good enough just to try it and see if you prefer it

I owned a SR4 with two Mates a few years back. We fibreglassed over over the holes. Made a huge difference when waterskiing! and didn't notice any significant difference to stability at rest.
