Reduction gear problem of Yamaha Super Jet

 This pic is after dismantled reduction gear.

Problem is reduction gear won't return to original position after engine start.

See this picture of blue circle, it is missing holder arm of clutch weight holder plate. This is cause of problem as clutch weight lost hold and stuck to housing. When this problem happen engine will keep run after start however reduction gear also keep turn as well and that mean starting motor is turn too and very much high speed.

Do you understand what I'm saying? In short usually reduction gear will return to original position after engine start and disconnect transfer between flywheel to reduction gear but if doesn't reduction gear will keep turn also starting motor turn too.

In worst case starting motor will get burned and damage cause by incredible high speed turn.

This reduction gear are use all Yamaha model except 4stroke model also all Kawasaki.

Yamaha and Kawasaki are both same reduction gear but only Yamaha supply service kit for reduction gear as holder plate and weight holder spring. However these service parts can be use for Kawasaki's reduction gear.

Engine won't keep run of Yamaha VX110

 This motor won't keep run as #4 cylinder is no comperssion. Removed head cover and check valves condition.

 Yellow circle is show #4 exhaust side camshaft and valve lifters.

This motor has 2 of valves each cylinder. Left side red circle valve lifter is up position as valve is close but Right side yellow circle valve lifter is stay down as valve is leave open (seized by rust)

 If valve is lightly seized, it will have a chance to back in to move valve after engine start but this motor didn't. Now this motor needs remove haed cylinder and service.

Broken engine mounts and ski didn't run of Yamaha FX-HO

This customer didn't good look after of engine room last 4years since brand new. So this motor and around parts had corrsion and rust becasue he didn't good rinse and spray after use.

Finally all engine mounts were broken (peel off from base) when he stack sand bank.

All engine mounts were broken and engine move to forwards.

Also coupling move to forwards too because drive shaft didn't turn as ski didn't run.

Lift motor.

Only engine mount base left

All engine mounts completely peel off damaged by corrosion. 

Also this center bearing housing was problem.

Oh boy! this one peel too of rubber and housing. This is should one peices parts, must be damaged by corrosion.

Both parts are wear and tear parts as you have to replace one day but if bad look after your engine room that may cause to corrosion, rust and damage so quick.

If you want to parts life make last longer, better to rinse engine room every after ride.

Replace of jet pump unit of Kawaski STX 1100

Initially this ski was just replace impeller as impeller was damaged and too much gap.

 Disconected pump assy.

Water was sitting inside of bearing room as needs replace bearings and seals.

 Impeller was bent and worn too much. Most case it can repair but this customer want to replace to SOLAS impeller.

Unfortunately impeller housing was damaged and won't fit brand new impeller.

So in the end replace all parts of jet pump unit except impeller shaft.

Brand new! looks good.

A part of menu,

My favorite ! Mos Cheese burger. Beef patty, cheese, onions, special sauce and a sliced tomato. It's yummy.

Teriyaki burger is famous Japanese taste burger.
Beef patty, a plenty of lettuce, Teriyaki sauce and  Japanese mayonnaise.
 
They make all burger after order so it have to wait around 10min after order but you can eat just cooked burger at any time and taste much better than McD and H-Jacks.

Pressure leak from fuel sender of Yamaha GP1200

This GP1200 came to shop for service. Then found water sitting in fuel filter. Also about 200cc of water was sitting in fuel tank.

  Inspected where water get into fuel tank and I found pressure leak from top of fuel sender as bubbles come out.  This top of fuel sender has indentation because if water sitting on top that through gap into fuel tank. Also this pressure leak from fuel tank may occur to fuel leak and in worst case it will have a chance to explode jet ski.

Dismantled fuel sender. Hose fitting was damaged by corrsion 1of 4.

Base of sender had few cracks as need to replace.This ski used over 300hr and 12years old, it was due to replace.

Replaced fuel sender assy as improved type of top.

 Better to inspect fuel leak on a regular basis for safe driving as save your life.
