WELCOME TO THE PAINLESS STORE!
The MOKAI™ is one of the most versatile watercraft of it's kind, giving the opportunity to go places other motorized craft cannot imagine. With some modifications it can be even more versatile and more reliable. Since 2011 I have been dedicated to making these watercraft as user friendly and reliable as possible and there are several upgrades for every model from 1999-present. I am a solo operation, so some orders will take time to fill, please keep that in mind when ordering.

Q: Is any modification required to install the Painless Clutch?
A: Only on the early models without the splined pump shaft, and Subaru ES-Kape models. Otherwise no, the Painless Clutch simply replace the existing factory coupler/pulley.
Q: My pump shaft is showing a lot of wear, is it ok to use your coupling system to stop it from stripping?
A: While my coupling system will prevent damage from occurring, it is not recommended to use worn parts with it. It is recommended that you send your pump to me for repair first.
Q: Do I have to take the coupler retention cup off to install the clutch to the crankshaft?
A: It is possible to use a 1/4 drive 1/2" socket, through the back of the splined coupler, to install the clutch. Please follow the directions provided for a trouble free installation.
Q: Why does my clutch make a ringing sound at idle?
A: This is caused by the idle being too high, and it's keeping the clutch right before it's point of engagement. Adjust your idle speed accordingly and the ringing will go away.
Q: Why does my clutch make a ringing sound during engagement?
A: This is normal for engagement speeds set faster than 1900 rpm, the clutch drum is acting like a "bell" and can make some noise during the in-between stage of engaging with the clutch shoes. If you can achieve an idle speed lower than 1700 rpm, I can lower your engagement speed to 1900 which is virtually silent after break-in.
Q: What makes your pump rebuild different from the factory rebuild?
A: A lot! I use a completely different design that utilizes a thrust bearing and a totally different sealing system that positively seals the housing so I can fill with Amsoil gear oil. While the factory method has been in use for many years, just about every pump I've rebuilt has been full of water (to include the new ES-Kape and 2.0), and relying on the bearing's seals to keep the water from destroying them and washing out the little bit of grease they contain. The stock bearings were never intended for the axial loads they are being subjected to, and enormous amounts of friction and heat are the result. This causes pressure in the housing to escape past the front seal and allows water to be sucked back in during cooling (like a preserve jar it creates a vacuum) while stopped. My design uses bearings meant for axial loads and a smaller diameter seal which is better for no heat buildup and better reliability. I also repair any holes in the housing from casting defects.
Q: How did you get an ES-Kape to go 20 mph when mine won't even do 15 mph?
A: A high compression EX17 cylinder head was installed along with my water cooled exhaust, to give the motor more compression, thus more power. Plenum was enlarged for better cooling and a separate cold air intake was fabricated. Weight plays a big factor in top speed also, I weigh 165 lbs. Every extra 15 lbs seems to drop the speed approx 1 mph.
Q: How did you get the 2.0 to go 27 mph??
A: I converted the bow to the gas tank, so weight transfer balances the boat for proper planing. That also lightened the boat 8 lbs since I removed the gas tank and fuel pump completely. I'm running a vacuum fuel pump driven by then intake port that I installed a pulse fitting into. I am running my muffler for better flow and my stainless intake grate flows more water too, combine with my jet pump thrust bearing conversion there is more power freed up to push the boat faster. To top it off I lightened the boat further by gutting all the electronics and going direct cable control.
