    Tohatsu 9.8a durability in salt

    What I usually do with new out of the box motors is remove all their visible bolts except exhaust and cylinder head bolts, grease them with high quality marine grease, assemble and torque them back and voila!!. Will never break any bolt's head again... Happy Boating

    Going over to inflatables.

    This triming the motor up on a manual trim motor it's a highly ranked word of mouth tech fallacy, If you read closely the Motor's and Inflatable Owner's Manual will find out that on both the motor should ride perpendicular to the water level, that's with AV plate riding same for the prop to...

    Merc's 4 Stroke 20 HP Carbed Motor.-

    Thanks both, Last time I did so as per your explanation the tiller was very stiff to rotate, should it be a smooth engagement say Forward while throttling ? If, so definitely need to lube all the associated mechanism. This motor has been sitting too darn long unattended as the majority of my...

    You're welcome, If going boating with say 4-5 up on constant basis and plan towing a sailboat too out of trouble get a 40 HP, is that 3.45 Rib a short or long shaft transom ? Which other HP option is there going down from a 40 HP motor ? Happy Boating

    Fuel problem

    Yep, test with a different fuel tank and fuel hose or with current fuel tank and a new fuel hose, current hose's connectors may already be dried, worn, hardened, o'rings letting air in and motor missing specially at high rpm... Happy Boating

    Merc's 4 Stroke 20 HP Carbed Motor.-

    So, in what moment is the shift rod being seen engaging up or down, there isn't a side shift lever on this motor as to engage F or R. The motor isn't running at the moment, need to check several things before first start. Happy Boating

    Avon seasport 3.45 + 55hp Yamaha?

    Will this be your first experience running overpowered Ribs ? That Rib is not large enough to run a 40 HP that's why the factory recommends max 30 HP, for instance my Sea Rider 340 Mtr Rib it's only rated for min 20 HP motors and if with boating experience max 30 HP motors whether being tiller...

    Avon seasport 3.45 + 55hp Yamaha?

    That 3.45 Mtr is rated for max 30 HP motor, It's not the weight of the motor, it's all about Max HP rated for which traducers in power on the water.. Post a pic of the combo Happy Boating

    Merc's 4 Stroke 20 HP Carbed Motor.-

    Came to my hands a clean but neglected F20MLH motor which has been sitting well covered for the last 4 years, has not been winterized nor flushed with fresh water in it's entire life, has low run hours on it, was used to power a medium dinghy as a yacht tender. The fuel tank and fuel line are...

    Avon seasport 3.45 + 55hp Yamaha?

    Is that a tiller steering or remote model to start with ? Check which it's the max HP factory stated for that given size. A 30 HP well propped motor should fly that light Rib straight to Mars, 55 HP is darn too much associated weight and power, could achieve a nervous planing attitude and lose...

    Recommended PSI

    Has the boat experienced a notorious hull deflation issues when top inflated to when floating once on water after some minutes rest or while boating. On warm days probably not, should be very notorious in cold water escenarios. Can always re-inflate to max working pressure with a hand or foot...

    2020 Yamaha 115 vmax cooling issue

    If an impeller gets highly screwed while a motor's lower leg sits out of water sitting on a transom, hoist, swim platform on warm days should not be deformed as seen in pic. In this particular case any other non hidden rubber piece would go the same route. Now imagine the extremely high daylight...

    Removing carb from Tohatsu MFS 20C

    Don't have any personal experience whatsoever in whether straight fuel run in carbs will gunk or not any carb if sitting for too long, but if boating in salt water it's the perfect excuse to run the carb dry while flushing the motor with fresh water soon after returning to dryland. Other point...

Can test the lower leg in a bucket filled with a high water level and spin the drive shaft CW with a drill machine attached to it as if the motor is working with attached powerhead. check if leaks and where is the leak located. What is...
