Hi guys, My CMB 21 LS, after about 20 tanks, I noticed that the big end of the conrod have a little "freeplay" that when I turn the piston to TDC the crank could be turned a little bit without the piston moving due to the freeplay. I noticed that the copper bushing of the bigger end of the...

Hi, I have a question for you engine gurus. Some 21 engines, like the CMB 21 LS, have the option of a "turbo" backplate. Can someone tell me the performance difference between a "turbo" and a "regular" backplate, is "turbo" backplate really useful, and how does "turbo" backplate enhance the...

I have a CMB 45 Evo 2/2 that had ran less than 10 tanks, but already had the con rod big end seizure problem three times already. Everytime it happens on shore right before throwing the boat into the water. The mixture has been set so rich that on start the pipe would split out a lot of oil. I...

Guys, Yesterday while I was having so much fun on my boat with a newly balanced and modified prop, all of a sudden the flex shaft broke.... :( That shaft has only been ran less than 20 tanks, and always cleaned and greese after a day of running. That prop I lost was a result that took me...

Guys, I have a Microburst 21 running a CMB Valvola gear box at 1.5 reduction. I used to run X447/3, and seems the prop is over reving a bit. I then changed to a X450/3 and the speed of the boat becomes much faster and handles turns better. Now, I am contemplating whether I should try putting in...

Hi guys, My friend have a new CMB 45 Hydro/Cam engine with CMB Evo 2 pipe on a deep V, running Morgan Cool Power 30%. For two weeks we had had a very hard time getting this boat running. Since there is no "idle needle" on the carb, we could only adjust the main needle. However, if we adjust the...

Hi guys! I would like to pick your brains here. I am a newbie. I notice that everytime when I put the boat (A surface drive Microburst 21, X440/3 prop) onto the water, the boat would accelerate very fast, but this "boost" soon died out after a straight of 30 feet, and the speed of the boat...

Hi guys, I just took a newly assembled 21 Seaducer 2 to the pond today. It is being setup as surface drive, with cg set at 1/3 from the back at empty tank. As the boat pick up speed, it rocks left and right on the straight, and during turns it tends to slide sideways. The rocking and sliding...

Hi, I heard a lot about the goods of having prop balanced. I just get myself an Octura prop balancer, and tried balancing my 440 2 blades. It is not that difficult to get the blades balanced. Later with the 440/3, I spent almost two hours trying to balance that prop, but at the end still I am...
