    Time to upgrade. Looking at 5.0 MPI w Bravo 3

    Wait a minute . . . You want to upgrade your boat and are considering a boat that hit a rock, the outdrive is damaged, and you are concerned about doing a compression test on the engine? Don't waste your time. I would suspect for the time and money that it would take to put it all back in...

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    Yes, when I pull the boat, I should be able to take the drives off, clean out any debris and backflush everything. If I have enough time, I might do the poor man's fix on the delayed shift.

    Here are some before & after 'tying' the cooling systems together . . . 1,000 RPM . . . 2+ psi difference with Stbd higher. less than 1 psi difference, stbd still higher . 1800 RPM Stbd still higher by 2+ psi Stbd & port about even . . . . The stbd engine psi max'es out at 15-16 psi, while...

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    That is why I have the sea water strainers. I my area, it seems that stuff grows inside the outdrive water duct, dies over the winter, then detaches from the water duct the next season, where it blocks the intake line at the bell housing fitting. I've had this happen twice. Once was the...

    Engine problems while on vacation

    I know that paint in the cool fuel was a problem with the Mercruisers, not thinking it would be the same for the Volvo-Penta engines. Is the remedy a new fuel module?

    Don’t know, I didn’t have the computer with me. Maybe this week I can do a computer recording. I ran it for a couple of mins at 3800 and no Guardian mode. I bet if I went WOT it would go Guardian 🤔

    Morning coffee epiphany. The flush line is only 3/4” ID, so it is a bit restrictive, but it seems to help. With this - the bets on the ‘shell stuck at the bell housing’ are looking good. 🤣

    2016 Mercruiser 6.2L ECT DTS Axius Cooling System Issue

    Quick update. . . The P/S cooler is hopelessly buried under other hoses and the Popeye valve. So, that may be a project for another day. As a work-around solution, I tied the 2 cooling systems together using the engine flush feeds. White hose in the picture below ( but don’t tell anyone that...

    My boat is being a boat . . .

    Here is the jetty that protects the harbor. It used to run all the way across to the right, meeting the land. One of the hurricanes about 40 years ago took the top layer of boulders off. I guess the authorities forgot to fix it . . . . . It seems like once things are built, that's it.

    Formula with Big Blocks . . . We looked at a Formula 330 CBR, but it had 350 MAG SeaCore @ 300HP each IIRC. Seller wanted 20% more than what we were looking at for the CY 338 boats. :rolleyes: The Admiral did not like the cabin access door design. I do miss BBC Gen6 rollers that were on the...

    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.
