    New prop recommendation

    FYI I stated my WOT with the Mirage in my first post. Spec for my engine is 4200-4600 so at 4300 I am in the range. I will almost never run the boat at these RPMs. I could afford a few more RPMs on the top end though.

    New prop recommendation

    So I am considering Solas HR Titan 4 blade or Turning Point Express Mach 4 or Mercury Mirage Plus (these are pricey) 3 blade. It is my understanding, when upgrading to a 4 blade prop the pitch should go down 2". The failed prop and aluminum spare are both 17 pitch so if I upgrade to 4 blades...

    Rehab SportCraft 222 1983 deep V hull cuddy walkaround

    I usually just catch a BUZZ, that's about it. I am not into fishing and usually bring bad luck when I go. My friend keep promising a large Striper but few times I have gone (not this year) we catch nothing. This was last week off the coast of Belmar on my friends boat.

    Rehab SportCraft 222 1983 deep V hull cuddy walkaround

    Glad to see you back, Now that the boat is on the hard haven't been around much. My friend has been out off the NJ beaches and caught few large stripers. Of course if I had gone with we would have caught nothing. Boat is coming along nicely. Wiring looks great, better than some of the pros I...

    Gen VI 7.4L Valve tap

    I have lived near the New Jersey shore my entire life and have only been to Long Island Once and I did not even go that far out LOL. Both the BQE and the LIE were so much fun with a manual trans pickup. Long ago I sailed from Conn to Block Island on a 37 ft. I can see the Long Island sound...

    Gen VI 7.4L Valve tap

    Believe it or not I reused them during my engine replacement as they seemed good at the time. I ran them 3 season in Barnegat Bay (mostly salt) and the Toms RIver (almost fresh) where my slip is. So they don't owe me a thing. You can see the rust staining on the gasket and also the...

That friend and I have not spoken in 10 yrs for reasons only he knows but from what other friends have told me he still has it plus like 4 others. It went through a 4spd conversion then back...

    Gen VI 7.4L Valve tap

    Well here we are almost mid march and the third Monday in a row with temp in the upper 60s (saw 75 on the thermometer in my truck) so this day I took off to pull the head and figure out a game plan. To my surprise bodean1's post 36 was the winner. "I still think it's an exhaust leak...

    Just acquired a 170 Horizon. Assembly required.

    Thats a sweet car looks pretty solid. Here in the rust belt they all rotted away. The ZX turbo engine should make it go great. Mine go a new home with the sale of the Satellite, should help it stay nice for years to come. You can see some boat parts from my boat project. 7.4L Valve tap...

    Just acquired a 170 Horizon. Assembly required.

    That's what I am hoping for, a low mileage original 70 Datsun 240Z just sold for and ridicules $300K. I have owned a 280Z, 280ZX and 4 300ZXs that I have driven. Drove the first 2 as daily drivers logged well over 150K miles between them, Then finally bought a really nice white with red 87...

    Gen VI 7.4L Valve tap

    Over the weekend my GenVI 7.4L developed a valve tap that can be clearly heard in the attached video. Using the method described in the Merc Manual i think I have isolated it to the Exhaust valve on number 1 cylinder. From what i read this engine should have Hydraulic roller lifters. When the...

    Last weekend we met some friends out at Tices shoals a local anchor spot, in our Sea Ray Sundance 250, when we first got there I switched over to what I thought was my start battery and tried to re start the engine with out success. Switched back to both batteries and she fired up no problem...

    So today I installed a new Impeller and pump housing on my 7.4L. This is the engine mounted pump with the fuel pump mounted to it. I started this morning by removing the entire assembly so I could change the gear oil in the fuel pump cam area. I then install brand new Mercrusier parts with a...
