Here are some examples of plugs & diaphragm behaviours for better tech understanding.

Pic-o1- Comparisson between Asian and Zodiac diaphragms
Pic-02 -Asian diaphragm central pin fit
Pic-03- Zodiac diaphragm central pin fit
Pic-04 -Transom outside plugs & diaphragm comparisson sizes

Have changed all Sea Rider sib water plugs for screw type rib water plugs + zodiac diaphragms, are much better and seals perfect on transom, Final Solution: Go to a Zodiac distributor and buy spare sib diaphragms, change your current sib asian diaph for zodiac ones, will perform excellent. I'm not recommending any particular brand, if in UK can find Avon type that fits asian plugs and seals well, then be my guest. (Consume local products)

If your diaphragm is not sealing correctly and need interior sib water evacuation, open stopper,accelerate engine at a non planing speed to keep sib at 45 angle to evacuate all water, once completely evacuated procede to put stopper back. With a good sealing diaphragm you can have plug stopper off/out at all times.

Bought a Zodiac diaphragm and tried it out today, still letting in water. Looking at the Zodiac diaphragm the centre pin is narrower and therefore a looser fit than the original. Anyway had a great day out winter sibbing so really not too fussed.

Thanks.

You can wrap teflon white tape on central pin to fill excesive play and auto center better diaphragm position agains plug base. Cut to desire height. Put a ball of paper tight against diaphragm, get yourself Abro gasket maker or a good silicone, remove lid, put tube nozzle in middle of central diaph pin, squeeze untill the inner central pin is completely coverd by gasket maker, this should make the diaphragm to have a tighter fit against interior diaphragm base and seal better.

If possible remove complete plug from sib, make this process outside so to center better the diaphragm before sealing other side. Let dry al least 24 hours defore sibbing again. Good luck !!Something positive should result. A pitty that Zodiac diaphragms arte pin thinner than current plug in use.

If it has side screws just unscrew outter complete valve, if doesn't have screws, is a 2 piece screw type valve, will need to remove the transom inner part to get plug out, on pic 4 will see most comon water plugs in use. One of them must match yours.

Have bastille type on my Lodestar 2.6

It started leaking this year but I discovered that it was down to poor fitting and not a problem with the valve itself. Removed it, reassembled it properly and now good as new.
