If on a trailer you don't need to close the sea cock since it cant suck in anything. ( Note that during winter storage you want the seacock open if freezing is possible) An interesting fact is that in some cases, lake water has more bacteria and pathogens than sea water. You process to flush and...

Those tabs are for twin motor application where one motor is counter rotating. For single motor or twin normal rotating motors you need the anode tab with a fin. A flat one will do.. Otherwise you probably will experience steering problems ( excessive force needed to turn one way and /or trouble...

The only sure way to 100% prevent scale and odor is to not use the head:) If your head is salt water fed, then flushing it just runs dirty sea water into the holding tank. There are chemicals you can add that will reduce odor but over time things will need maintenance. If you have a fresh water...

Yup, that could be but I would expect the shop to know better. I wonder who did the hubs. Was it a motor service center or as I would recommend a prop shop?

One more piece of info about Optis if that is the motor you have. The pee stream comes from the cooling water feed from the pump to the air compressor. It is possible to have a good pee steam but no or reduced flow to the heads. If the poppet is stuck open, the heads will get hot ( starboard...

As stated earlier in this thread; Although your symptom is typical for a stuck open poppet valve, as mentioned, a weak pump may also be responsible. It's hard to tell since the only way to know is to judge if the pee stream at idle is normal force. If the poppet is bad, that won't affect the...

The water in the tank tends to grow some slime especially in warmer climates. That slime clogs the screen in the filter. That can reduce flow or shut if off completely. The only way to reduce the slime growth is to frequently drain and flush the water tank ( draining can be a pain) or adding a...

On the Yami oem props I have had rehubbed, there is no insert per se. The center bushing is potted in place with some sort of urethane goo that sets up forming a bond between the prop hub and the prop shaft bushing The last prop I had done was a original 17M Saltwater Series model ( Stainless...

Follow the starboard cylinder bank hose connected to the thermostat. If you have a 150 Opti, that hose (except on early model years) runs directly down the side to the poppet valve. You may need to remove a few electrical connectors and fuse holders to get to the poppet

Great photos. It brings back memories of a job I didn't enjoy very much.

The damage is severe but as long as the 'flap' between the two open cracks is sturdy and doesn't flex, a cheap fix can be done. Just make sure the cap is tight to the hull and doesn't move when lifted or pressed. Since the major damage is under the rub rail, you can patch with MarineTex or a...

The T-( can, just use a light coating. No need to make a mess.

Did you install and use the props right after you picked them up? Some of 'caulking' product that are used need a few days to fully cured don't honestly think that was your problem. I think the workmanship was poor or there was an issue with the materials. I would bring them back and ask to...

I missed you statement that the motors are 2s Mercs. The good news is that the poppet is not behind the PCM but it is very difficult to work on without removing the lower cowling and that will can be a very difficult job in general and kind of impossible in the water. The difficulty of the job...

OK that makes better sense. What do you expect the twin props to offer over the single prop motor on a twin application?

Thanks for your input. I would only look at non porta potty installs. The newer models have a decent swim platform and a side facing ladder but the thing that worries me the most is the lack of a transom door. As we get older, it is more difficult and potentially dangerous to have to climb/slide...

Is there a screen/filter between the tank and the pump?

Are you getting one motor??

There are threads on the poppet valve and what to watch out for. Personally, I would prefer to have the boat out of the water but to an extent, that depends on the engine model. For example on older SX motors, the popett is behind the ECU and that has to be removed along with the cables and...

Boeshield T-9 works for me.
