Looking for a little info on jets as I am a new jet driver.
First off I have an 1852 with 70hp Yamaha 2-stroke (donít hate me, I could afford it). I have put 40-50 hours on it in the last month and a half. I have sucked a lot of rocks and the impeller is most definitely dinged up.
First: Can I up grade the factory impeller for a little more speed (I already have bigger engine envy). I have heard some of the stainless argument and I take from that, that it will not help performance on any engine less than 100hp, but that it has longer life.
Next: 4600 rpms is all I get out of the engine. I cruise around 3800-4000. I have heard others talking about much higher rpms. Is there anything wrong with my throttle?
Last (for today): What is the best way to mount seats, rodholders, cletes, ectÖ? I have already had seat screws pop out.
