    Lowering the bunks . . .

    Yes, on the target (bow) bunks. As for a longer trailer, it is already 37 feet long, so I'm not wanting to make it any longer. With the truck, I'm at about 56' long.

    Lowering the bunks . . .

    I'm actually hoping to get to 3" lower, but I want to see what 1.5" looks like on the trailer.

    Lowering the bunks . . .

    Yup . . . very shallow.

    Lowering the bunks . . .

    Braking is when I need to stop. It seems like the surge brakes are not doing their thing and it is all up to the truck. I’ll figure it out. Usually if surge brakes are working, the trailer will stop itself.

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    We went locally today, so as not to risk it. Only 12 psi at 3400 - 3500 RPM. It was at about 15 psi coming out of the harbor, then dropped once getting up to cruising speed. . . . it certainly seem like something is floating around in the raw water side and gets sucked into a restriction at...

    Can you change a Tohatsu 9.9 hp to 20 hp?

    Understood- it does look to be the same powerhead. Not sure the upgrade is all that feasible. Maybe get the 20 and get a decal set for the 9.9 🤣

    Lowering the bunks . . .

    Since I might be taking my boat out in the next few weeks for some un-planned maintenance, I wanted to lower the bunks to make retrieval and launching a bit easier. The trailer has quite a few adjustments. . . height, spacing, etc. The increments are 1.5" on the height, and it looks like can...

    Yes, I can play back any of the data from the recording to see how they relate. :) The software only let's you choose 3 elements at a time for graphical display. :cautious:

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    The P/S fluid cooler is P/N 8M0095482. I believe it looks like this . . . I am wondering if it is a straight-thru cooler as Dubs mentioned, rather than the honey comb style.

    We should take odds on the likely causes and see who wins . . . :LOL:

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    Just reading through some dialog and comments about EMCT overheat issues, I came across this one comment . . . "Too many things to go wrong with Smart Craft. Gets your blood pressure up and your wallet out. This will be my last boat with SC. Analog worked well for many years, KISS" Funny...

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    Quick Update . . . There is a temperature sensor at the bottom of the exhaust riser - Mercury P/N 885342002. So, I assume that is what the 'EMCT' temperature readings are from. I answeredmy question, the EMCT is the raw water and the ECT is the coolant. I can run a recording of the port...

    Bravo 3 are stainless steel propellers - no hub. I have the 4/3 set on my outdrives. you can get a 4/3 set if you want to try it - about $2k :unsure:

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    Yes, that makes sense. Particularly if a pice of the impeller broke off as the next stop is the PS cooler. Just have to find it at the back of the engine.

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    My thoughts are that if the restriction were at the end of the sea water flow (exhaust) the pressure would be high, if not higher than it should be. If the restriction were earlier in the coolant flow, then the sea water pump would be 'starving' for a full supply of water. Another thing is...

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    Thanks for the replies . . . The water pressure sensor is buried amongst hoses, not an easy swap. I suspect that the pressure is probably reasonably correct, given the exhaust overheat. The impellers that I removed last year were in very good shape. 100% intact. The water pressures last...

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    Quick update . . . my video stopped a bit short of the full recording. The stbd side EMCT got up to 186˚F while the port side was at 161˚F . . . so 25˚F difference. Not sure if that is significant enough or not. Perhaps so on a WOT run. I am also not sure what the EMCT is reading Coolant...

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    Greetings, Branching off from my 'boat is being a boat' thread, I am posting about an issue with the starboard engine cooling system (Serial # in my signature below) Keep in mind that the engines in my boat are the in-house Mercury built engines, not the GM 6.2 that preceded them. Fun Facts...
