Re:CMB On a K&B Lower
Ok, well each to their own with the lower units, but I have no profit in the matter. I will give you my honest opinion. I have seen both, and have ran a lawless myself. Lawless are ok, look great, but have really soft metal. Myself and others in the club have had bent skegs because of minor bumps. The guys in the club who run the 7.5 foot, well they swear by them, never see them hook near as bad, and really the advantage is that you WILL NOT break as many cables. The 7.5 cable is much larger and stronger. The guys who have been running them over the past two years have broken 1 each, as to others many on the 3.5 cables. &.5 foot is the way to go if you want to race and also save money on cables.
As far as injecting the lube, will if you look at the mounted engine from the rear of the boat, you need to look at the side of the lip where the engine and lower unit are joined. There will be a tiny whole. This is the same on the 7.5 K&B and lawless. You take an oil can, or some type of squirt gun( like a an old oil can) and squeeze it in until it runs out ofthe whole down near the drive dog. Some guys use grease, but you must take the cable out ever time. Most of the racers here inject their own lube concoction after and before every run of the engine. This keeps a good coat of fresh lube in the tube.
As far as the STP, well I did it because Irwin told me to. I have almost taken it out of the lube mix, because of the Transmission fluid a nd the 20 weight oil.
The ATF just really seems to join easier with the 20 weight and ATF just really has worked for me.
I belive in experimentation with the lube. Is used the STP and 20 weight alone for a while, and I broke shafts. Once I started in with the ATF... no shafts have broken, but I lube after every run, no matter how short it was!
Hope this helps.
