Check what's the min-max wot rpm range factory stated for that motor, go for a wot run as will usually be loaded and report max achieved rpm. Will know if in need to go for a less pitch prop to bump wot revs up and by how less pitch number...

Seems those mentioned brands are the only ones that don't use shims as such, but use washers instead with specific thickness, all the rest use shims and washers on their prop shafts mechanisms. But we're not going to argue about that LOL!!

All pinions are precision machined worked, the shims are used to provide the correct lash between pinions to wear in nicely, will asure that all lower legs use some form of shims upon further investigation...

When priming the fuel bulb hard till fully firm, is there fuel spillage going on that carb. Check that the needle float is adjusted to factory specs, the needle is sharp pointy looking and the needle's valve is impeccable clean and shiny, inspect with a flashlight to check that condition.

If a prop is used with a unsuitable thrust washer/spacer or without one while hearing a high grinding noise, will end sanding the rear of the prop and the front of the prop housing as well....

A gearbox with already shot pinion, bearings won't say much at all. The gearbox lash is something that comes factory adjusted to each motor brand specs. Inside a gearbox there's many shims and washers diameters to play with and proper tooling to adjust spot on proper gear lash. It's normal for...
That's a 26 year oldie motor, if always have burned 50:1 fuel/oil ratio thru its entire life that motor needs a desperate and urgent full decarbon process. Buy a can of :
Follow instructions and squirt at least 1/2 can contents thru the carb in small intervals for the motor not to die when...
If the pinion bearing hasn't gone south already should find repetitive metal shavings at future gear oil changes. As this is a second hand motor probably the previous owner changed the gearbox components that were installed with inappropriate shims and washers, that's with too darn tight pinions...
Not an issue destroying a lower oil seal with hundreds of clocked run hours compared to the upper oil seal removal which is piece of cake with whipped cream on top...

Which type, length of boat is the current motor powering ? Wot test with the number of souls that will usually be on board on flat calm water cond.

Welcome to IBoats,
Which wot rpm did the motor achieved with a 16 pitched prop while running heavy loaded on flat calm water cond. ? A 15 pitch prop will rev more than a 16 pitched prop. Can compensate that situation adding more passengers or throttling bit less....

Which of the 3 mentioned anchoring methods do the inflatable community is currently using, specify length of boat, chain and diameter and if works well for your type of beach, river, lake requirement which is ?

Have you replaced the old prop for same new one ? If not, probably the rear prop spacer is too short or different and the back of the prop it's grinding against the front of the prop shaft housing ?

Thanks both, but the original tech inquiry was : how to remove the big lower oil seal without tearing the motor apart ? Recomendations, something that works for you ? Not an issue if in need to tear it apart in pieces as it's just hard rubber...

Without any wot rpm posted data as currently loaded with current 3 blade prop whichever pitch is it it's a bad idea going towards a 4 blade prop blindly. For a correct prop maximization need to know the wot min-max rpm range factory stated for that HP motor to be compared with the wot rpm...
