QBhoy, now the expensive brand very well, got it, that's 40 HP for max passengers allowed, nervous behaviour when lightly loaded at full grip specially when running any tiller 40 HP at max wot rpm range factory stated...

Definitely needs an urgent transom height modification. To start with there's a big suspended o'ring right in middle of both motor clamps (X) which needs to be removed if plan going for a neat middle transom shave.
The max clearance between pan (a) and upper swivel bracket (b) is 2", so...
This is a prime example on what you should never go after when powering a heavy boat with a portable under powered motor. Scenario :
2.0 K Kg wooden boat, XL shaft powered with a 2 strokes Yam 25 HP motor. The moron as seen in pic it's undergoing its third in a row powerhead replacement, due...
As a first step need to have that tach working and reading wot rpm's right, then going straight for a slip hub test with current installed prop and go from there depending if it's shot or not to troubleshoot other combo parameters. By pure ear sound won't possibly know at which wot rpm the motor...
The stated 10-12-14 % whichever fuel consumption rate goes on on a 2 stroke motor is measured running at their max wot rpm range factory stated. With a motor running so will need to throttle less compared to same combo running badly propped to attain same equivalent speed along consuming more...
Without knowing achieved wot rpm with 2 up once on plane won't know if motor is revving healthy. Is there a tach installed ? If motor runs healthy throughtout the entire rpm range, the combo could be drinking a cocktail of the following : motor is over propped, baddly trimed, badly transom...
Losing top reverse trust happens in 3-4 blade props compared to forward thrust, why would you need a speed demon prop when going in reverse for, reversing takes more time than forward thrust. If the motor was previously reveresing fine it's not a prop issue...

The motor revs up but with no back prop thrust right ? or doesn't acceerate at all which are 2 different scenarios? If (1) it's a lower gear case issue, something inside went kaput, whcih one is the issue ?

Yep, was 101% sure that were going to reply that. If we go for the conservatory 10% burn rate per HP rated will have 11.0 gal for the 110 motor and 9.0 gal for the 90 HP one, but with old 2 stroke motors it's actually 12% or tad more burn rate.
Assume the OP likes fishing with a fixed load of...
In such case shut the tank's fuel valve and run carb dry. As you probably won't know when will be your next boating day, turn the motor upside down and remove the fuel remains into a container. Preffer a zillion times to run fresh fuel on my next outing than stored ones for long time terms...
Unlocking any truly seized tiller shaft/swivel bracket assy will depend entirely on how tight both plastic bushings have seized themselves onto the shaft and internal swivel bracket as explained in post 8.
Regreasing through the lower grease nipple with a grease gun for the grease to exit the...
If leaks through the carb it's a float needle/seat issue, if leaks where the fuel hose attaches to the carb's fuel entrance it's a hose/clamp issue. What have seen is fuel leaking through the fuel cap specially during hot summers due to closed air vents which will increase exponentially the...
I like boating myself with larger boats along underpowered motors for such applications. Water Performance for me it's achieving the best prop thrust in all water conditions while my motors with maximized props runs at their max wot rpm range. With underpowered motors you can't possibly ask for...
