Ring 21 with Mercury Optimax 300xs

[voki]

Hi, I am new here and it is great to find that there are so many boats like mine still running. I recently bought a Ring 21 and am thinking of rigging it with a 300 xs. What top speed do you guys think is posibble? Any info on rigging is appriciated, what prop should I use, it is a sportmaster gearcase

Thanks

Come on Gary let us know what top end you are getting !!

I've never seen a 90 or mid 90's mph ring or phantom, not in ski race set up and not with 1 engine. Anyone being honest racing in F2 would say they are only doing 80mph max and thats on a fast flat day and maybe for 3 laps, and thats the leaders !!

If that was the case then wouldn't of held a national speed record up untill last year.

At Cardiff this year we were keeping up with the leaders on the first few laps with an old Ring 20 and a Standard 2.5 260 HP (in good trim!) we GPS just before at 77 mph (does need a good driver to drive through the Chining) I think that confirms Dangerous remark!!!! Mr Grimes used a tuned 2.5 280 to be sure of beating us !!!

Hi my dad used to race a R21 with a 2.4 bridgeport. he used a 24" 4 blade Rollar cleaver, think this may work for you too which we have for sale. PM me fo info and pics if you are interested.

although the power figure might have been some what suspect
i belive Burty managed more than 90
in a single engined p20
personally never understood why he didnt take it to records week

i run a r18 with a 225 promax and best weve ever seen.. gpsd was 76.7
so i can imagine thers more to be had than 80

With the Rib we managed 91.5mph with a standard 280 EFI, and we used to run 85mph offshore in slight chop, obviously it is very different to a Phantom / Ring being stepped, lifter, a Rib etc, but it did weigh about 950kg, so I think a Ring 21 set up for speed should be around a similar figure and certainly into the 80's?

[OCRDA]

Mid 80's with a good setup would almost certainly handle better with a 260/280 EFI though !!

My Bernico ran same speed with std 260 as it did with the 300xs (94mph) but more stable with the 260.

Good Luck

My "old" P21 ran 85-88 with a 250XS on gps.

Thank you all for the info, if I get anywhere near 85 mph it will be great, already have a 28P cleaver prop so Ill first try that and see how it goes
