    PROP size yamaha 250 2 stroke

    They are probably not burning more gas. Assuming you did use more gas and I am not convinced your method of estimating consumption is accurate, the gas must be leaking out somewhere. There could be a leak under cowling in which case the gas will end up flowing out the prop and may not notice ot...

    Winterizing Yamaha Outboards

    It's a little more complicated for someone without experience. How many of us ( myself included) at one time or another has broken a pitot tube hose of fitting:) How many didn't know there was a bolt hidden under the plug that covers the trim tab bolt! How many have wished they added a bit of...

    Which 0X66 is the good 0X66?

    Bring a soft faced hammer, plastic is OK and tap all over the hull from the keel up to the rub rail. Then repeat on the transom. Wet/rotten transoms are common. I can't comment on the asking price. There are many factors to consider.

    Which 0X66 is the good 0X66?

    Yamaha advises not to crank with plug wires disconnected. Normally a mechanic would connect a clip on switch at the starter relay to enable cranking. In that instance the ignition would be off. If you do turn on the ignition, pull the safety lanyard. That should kill all spark. The compression...

    Which 0X66 is the good 0X66?

    You have to be diligent checking and adjusting if needed the precision oiling system linkage. Sometimes a linkage part breaks and the oil pump goes to the most oil position which is OK at speed but not at trolling or idle. About the oil; Is there synthetic 2 stroke oil? Just use a good brand of...

    Winterizing Yamaha Outboards

    Read and follow the Stabil recommendations for storage. I have seen folks overtreat with additives and cause issues. Mostly that was with Seafoam but better to be safe.

    Which 0X66 is the good 0X66?

    The original 150s as I recall reading about were fresh water models. At some point in their development a model line geared towards brackish and salt water applications was introduced and named the Saltwater Series. As with all engines, maintenance is important and relatively simple. In...

    Drain lower unit

    If there is no water in LU oil, it can wait till spring. It should not ne stored empty. That is asking for trouble since the internals can rust. If in the worst case, there is water in the LU oil, the unit should be serviced but it if can't, it should be drained and refilled and serviced again...

    Trim tab pump 228

    If you are referring to trim tabs attached to the transom and by losing prime you mean that they do not stay where set and retract over time, then you have either of two things going on. The lines or cylinders have a leak. That should be easy to check or if no leaks, then the check valves on the...

    Cutting open anchor locker access?

    You should use a downcut blade. That is a type of blade where the teeth cut on the down stroke and not up stroke as a normal blade. If the blade is not carbide and depending on the thickness of the glass, the blade will wear out quickly. An angle grinder with a diamond blade will work faster if...

    Cutting open anchor locker access?

    I had this happen, the drain plugged and the locker overflowed. It did not drain into the mid bilge at first. Instead it soaked the cabin cushions and them ran down one side where it puddled. What was surprising was how much water my anchor line would hold when wet.

    Cutting open anchor locker access?

    You have to be careful with respect to the drainage of water in the locker. If you current arrangement drains water to an outside through hull ( clamshell fitting perhaps), you need to make sure that the lower edge of the access panel is higher than the drain. If it is lower, the water will...

    Seakeeper Ride on a GW Freedom 235 ?

    What is it, a 235 or a 325? I was just on a sea trial on a 26 foot CC that had Seakeeper Ride 400 series. The ride is noticeably smoother when the system is engaged. Note that the system corrects for roll and pitch but only at speed (10mph and up) unlike Seakeeper gyro that will work all the...

    Winter Battery Charging

    If the two batteries in parallel are not the same type and age, I would be careful. That said, if the batteries are in good shape and are fully charged, they should be OK without a need for the charger. That assumes that the batteries are disconnected from all possible loads, like auto pumps...

    Leaking fuel tanks 306 Bimini

    The sender if the tube type doesn't and shouldn't go all the way to the bottom of the tank. Therefore a certain amount of fuel could be in the tank without the sender 'moving'. As mentioned, the angle of the tank can greatly influence the readings

    Steering is Stiff

    One simple question. Do you know if whoever serviced your motor ever added new grease to the fitting on the steering tube (the place where the motor can turn.

    Steering is Stiff

    A significant difference in steering force between turns to starboard or to port on a single engine application can be a symptom of a mis adjusted trim anode on the lower unit. Alos if you hydraulic cylinder is a single ended model ( One end of the cylinder has a rod that moves in and out but...
