Thanks Jay
due to health & safety regs we cant run open/uncovered exhausts in our club ,no more than 65mm can be uncovered,hence why i do the false OB helps with looks but covers the exhaust to comply with regulations
I race with our club BMPRS and now have 2 cat classes for different engine sizes
I raced my last F1 for the 1st time and crashed out avoiding a dead boat ,been a wooden hull ended up been un-repairable. but overall the performance was blistering in both speed and handling,just my driving/lack of experience been on course with other boats let it down LOL
