    Alpha one gen 2 tapping at hard turning angle

    Good morning we own a 2006 Bryant 190 with the Mercruiser 4.3 TKS. Had to have a new upper and lower unit installed two years ago so went with an SEI it’s been great . We’ve had no issues, I did the initial gear oil break-in, and then fluid changes every year. I’ve noticed this year that if I am...

    Winterizing 4.3

    Winterizing 4.3

    Thank you, I will check the drain ports but they all had a good stream coming out of them. The entire lower unit is new just a couple of months ago due to another issue. So all of that was recently apart. Gimbal, bellows looked great and I serviced the LU after the 20 hr break in and have only...

    Winterizing 4.3

    Hey all. I winterized out ski boat today, first time doing this. I pulled the 5 blue drain plugs and let everything drain I then undid the hoses at thermostat and poured antifreeze down all the hoses till it was running out of block and manifolds on both sides, also was running out on the ground...

    4.3 prop

    I agree 100% on the four blade. I went to a bravo xs on my bass boat and I can plain at a lower speed. It doesn’t blow out in a turn and the boat just handles better. I lost 2 miles an hour on the top end, but could still run 72 by myself. It also pops out of the hole almost immediately...

    4.3 prop

    OK, got it, I really like the idea of a four blade Prop. I’ve run one on my bass boat and I really like the way it handles. I think I will order a 17 pitch, that should give me up into the middle of the RPM range hopefully around 4600, we do pull a tube and water ski, don’t typically have more...

    4.3 prop

    Hey guys, So we had to get a new alpha one drive due to the theft of our other one. It’s a 1.62. It had a vengeance 19 p prop on it so I decided to try a 4 blade rev 4. Bought a 19 pitch per merc prop finder. Boat runs great but can’t get past 4200. That’s at 45 mph. Do I need to go down to a...

    Mercruiser 4.3 port elbow hot

    So those two hoses that go to each elbow are item number six in that diagram do they not make those anymore? I cannot find them anywhere? I thought about replacing both sides just in case the port side was starting to collapse or restricting flow because I don’t understand why there is such a...

    Mercruiser 4.3 port elbow hot

    OK, got it, thanks for the tip. I wondered how much pressure or how tight those are supposed to be. What’s the word on these thermostat housing do they usually hold up pretty good, nothing visibly leaking. It appears to be original, new ones are pricey, about 400 bucks and difficult to find.

    Mercruiser 4.3 port elbow hot

    Yes, I have ordered the replacement balls and springs. I plan to swap all that when I put in a new thermostat, I ordered a 160° thermostat because that’s what it says it should have, and that’s also what the owners manual says from the guy I bought the boat from. It says that’s what it came...

    Mercruiser 4.3 port elbow hot

    That would definitely be helpful, I thought the same thing why is there such a sharp bend in those two hoses it seems unnecessary. I looked up the part number that is on that hose and it says it’s no longer available. I can’t find it anywhere.

    I have a total of six hoses leaving the thermostat, housing, one big hose on starboard for the circulating pump that goes to another large hose that goes back to the intake, two hoses is going to the bottom of the manifold and two hoses going to the elbows. I haven’t noticed any steam on the...

    Mercruiser 4.3 port elbow hot

    OK, well waiting on parts to show up, gonna tackle the water pump thermostat tuneup. See where it’s at after that, figured worst case scenario is I could take off the port elbow and take a look.

    Mercruiser 4.3 port elbow hot

    Thank you for the response, yes it’s pretty much the same rather it’s on the hose or at the lake. We’ve had it out three times in the last 10 days. Figure it won’t hurt to change the water pump since I don’t know when it was last done, just trying to figure out if I actually have a problem or...
