Hi my question is can I spin the head around cos my exhaust comes out of the front but i want it to come out of the side like yours also my carb is at the rear where the pull cord is thanks.
Where do you get your parts from I just bought a boat with a ez 25 motor and Im new to water cooled and I need new water jacket seals and I'm having a hard time finding them thanks
easy fix for this engine. new ring and maybe the low drag seals -those are terrible with longevity but give good BRAND NEW performance. meaning you dont need break in. its better for longevity to use stock oil seals and just remove the springs. the scoring on the exhaust side is from overheating /lean run. or not enough oil. also if u use a proper modern or race oil there wont be carbon on the top. also if u run meth/mixed gas.....also dont use meth gas it ruins the carb diaphragm. or u can get the new diaphragm from walbro that is metal. cant remember ,its a coil type contraption .expensive but it should last forever
HOLY!!. all im saying is NEVER hit anything on an engine. esp drive train. crank microscopically ruined . in the grand scheme of the low performance level of a zen style engine it wont loose much. also if ur not that great an observer u prob wont notice ,,but its bad practice . i like to see people workng on internal combustion engines tho ,so keep up the good work
Great how to video on engine break down . I'm sure I'll be needing this info recalled in my brain in the future. Okay enough chat, on to part 2!
Loving all your new videos!

I get most of them from gizzmo motors
gizmo and DDMracing
are the connecting rods the same length? if so the stroke length will be different, could change compression and head clearance
Lol funny u should say that, lol. You’ll see in part two
What fule mix you use ??
i use 8 ounces to a gallon. and i use saber 2 stroke oil

more rotational mass = lower rpm but more torque would by my guess.
id bet the original crank was why its a "modified" block, its a cnc cut and balanced crank to get the most power and rpm out of the motor.
