something wrong for certain EMM should reflect reality 115hp
next thing is to fix the sensor fault
check your injector tags to see if they match the EMM log if not EMM was substitured or eprogrammed for some reason.
Unfortunately there isn't much info to the level of detail you...
no need to tap hard .
To remove... Drill a small (NOT DEEP) hole in the plug and use a pick or small nail to just pry it off. When done cleaning everything incl side channel.... the new one is fitted in and I use a square head (Robertson) screw driver to tap it in (not to much just...
after you find and fix the cause ...
if you don't want to spend $131... line up the cracked pieces and weld them from the underside.
See several utubes techniques on welding plastic parts (glues usually dont work to good as these things are usually polypropylene based plastics)
I used...
This is a sudden problem after I had the motor serviced for a new impeller and a carb tune it happened the very next trip.
There is certainly relation or coincidence with the servicing of your engine and this " new " condition ...
If the shop is reputable they may take it back and have...
can't say but the water flow under thermostat control may not be sufficient to provide the same cooling as a wide open flow with no thermostat.,
if you do not feel like pulling the cyl head try a new set of thermostats has suggested by saltchuckmatt to get even temperatures on both...
pulling the cyl head to inspect water jackets isn't al that comlicated and only costs is a new gasket.
is this a sudden problem , evolving problem over time. ?
when was the impeller serviced last ? any chunks missing ?
salty or fresh water engine ?
mdl# ???
IF...compression is 60 try another meter with a short hose .
it should be decent like >75-80 psi. my 9622a 9.5hp run perfect at 65 psi so don't give up.
you may be just starving out of fuel.
I assume you have good strong sparks...on both plugs !
easiest to try is pump the fuel bulb...
what I said was a maybe....
your cut hose may have been the one feeding oil to the fuel line just before the lift pump.. Inspect your fuel route to see if you have alterations or missing T on the fuel line. Make 100% certain all oil lines to the crankcase are installed.
that cut...
the exhaust housing is full of carbon deposits & unburnt fuel-oil when inefficient 2 stroke engines blows out the cyl fumes when the incoming load of new fuel-oil fills in the cyl. space on the downstrokes.
Probably 30% of good fuel and oil is waisted by the 2 stroke design which is...
When it is struggling to start, sometimes it will seep dark oil out of the bottom unit right before the prop
most likely carbon and sludge wash out from extra fuel on those et oil plugs
You may want to consult the attached. On FICHT and ETEC engines up to about 2006 or so.... one oil feeder sends oil into the incoming fuel line to provide a mix of fuel oil undr EMM control . Check to see if previous owner did not cut it and fed pre-mix at 50/1
this link will list...
how about some more details as to what you want to analyse ...on what type of engine modern oldy ... ignition, timing , capacitors, coils modern ECU like EMM,s on ETECS etc...
making your own may be audacious .
time to buy the book to understand and service your engine there are no "primary" coils under the FW ... just 2 magnets built in the FW that spin around the 2 coils .

compression has nothing to do with sparks especially if plugs are just simply grounded to the frame and not themselves subjected to extra PSI's
crankcase is just a cavity to allow movement of internal parts. ..
remove the plugs stick a screw driver in the boots and confirm...
