    2006 Volvo Penta 5.7 GI limited rpms

    I’d have naturally thought the harness (along with a load of other things) would be different between these two. Have I got you right in thinking the new engine is a Gi or are you saying it’s a GL ? As far as I know, the Gi is a single point tbi and the GL is a carb. Your 5.0 GXi was likely an...

    Thought my boat would be faster

    Late 30’s would be good going gps I’d say. Trim and good prop is required. My boat will loose 10 mph or more without trim
  4. Q

    Tilt/Trim gauge stuck in UP position.

    Has it ever worked ? If it doesn’t move with manually moving the sensor potentiometer, it’s the gauge or the wiring to it. Failing that…just do what the old school do..ignore it and look out the back. I’ve got digital trim and analogue indicators…but looking out the back does the best job of...

    Question about control cable and water separator for carbureted engine

    Get a genuine racor (mercury sell one) water separating filter and you’ll be good. These have been fitted to engines like this and decades older for years now and all is well. Had one on an old 80’s merc 150 years ago. If anything is going to be a restriction, it won’t be that…as long as it’s...

    Carb to MPI problem 2011 Merc 4.3

    Hi. See that blue main harness plug…take that apart and get electrical cleaner into it. Straighten out the wiring on it there too. Doesn’t look to great there. Make sure nothing is earthing onto the engine block or elsewhere from any un capped unused sensors too. There are an array of unused...

    Wrong outdrive gear ratio

    20” enertia 3 blade usually. But it’s a performance hull with steps and pad. Will run a 21” to about 67 mph gps if it’s very light but terrible down low. 19” tempest plus 3 blade for water sports but will hit the limiter with that easy. Usually set up to run early to mid 60’s with 20” though...

    Battery issue Mercruiser 3.0

    Test the power at the battery when it’s running. If you’re seeing anything less than 13 something…

    No power from the top 2 cylinders

    Have you tested the coils warm ? What about the stator and regulator health ? Getting a charge back ok to the battery ?

    Freshwater Boat to Saltwater

    Zinc is what you want for salt really. The standard aluminium ones are for dual use, but could argue a slight compromise for exclusively one or the other. Not referring to other type aluminium anodes that are available. I’d also get some marine inhibitor spray for coating things in a protective...

    snapped driveshaft Mercury 2011 150 Optimax

    Sounds like a great experience there… These optimax engines have a rpm limiter built in. Usually around 100-150 rpm above the max rpm range figure.

    Boat choice

    Agree…although I’ve recently noticed some manufacturers of stern drives, trying to change things up…with their forward drive units. The props are on the forward end of the drive. Obviously that comes with a few compromises!

    Boat choice

    That’s true…when at a certain speed…but when they are running slower, their wide flat profile at the rear of the hull…also makes a huge hole in the water, to produce a fair old wake size. Wake surfing speed in particular. Modern models in the last decade from the big brands out there, do...

    Big differences, same power?

    It’s a good question to be fair. Unless the location of their power rating differs. One taken at the flywheel and the other at the prop.

    Big differences, same power?

    The new mercury 4 stroke engines from 75hp-115hp are the most extreme example of this I’ve seen yet. All the same engine, but different mapping and rpm ranges. All are a rather enormous 2100cc for that Hp. The 80hp version for example has a rpm range of 4500-5500. But the 115 pro xs (same...

    20hp Honda on Basstender 11.3

    May not apply…but those wee Honda engines that size are fairly heavy. Not sure what age your boat is..but some older boats have their rating with a lighter 2 stroke in mind. Also, most often..with boats that size and length…an engine that’s too heavy can absolutely ruin the way it handles and...

    Mercury Binnacle remote control - Gen 1 vs Gen 2. Worth the upgrade?

    As above. Well made and expensive unit that. It’s the cables that will be the issue. I’d keep what you have for sure. Much more able to stand up to an exposed environment than the other.

    Boat choice

    They can both be made to be a decent wake boat. Ballast etc. wake gates and all that. Just make sure that’s almost exclusively what you want the boat for though. Boats like these are amazing for it…but there are compromises made in terms of other uses for sure. If you’ve never had a shaft drive...

    Kill switch location

    Might not have one, at that age. Some remotes didn’t have them back then. If you do..and it’s remote control..it will be on the remotes.
