    Stereo Receiver Replacement Fail . . .

    After 21 years, the original stereo receiver in my Formula 330 crapped out . . . can you believe it :eek: :rolleyes: It is a Kenwood KRC-901 with a Kenwood KDC-C603 CD Changer and 2 Kenwood KAC-425 power amplifiers. I figured on staying with Kenwood for compatibility, etc. and got a new...

    Overheating Mercruiser 7.4L MPI

    I had a similar predicament . . . $330 to pull the boat and another $330 to go back in. So, I did what I could while the boat was in the water, and it was not until the end of the season after the boat was hauled for the season that I found 'the shell' in the outdrive inlet tube. My approach is...

    Dual Battery Setup, Starting from Scratch

    Don't let product marketing terminology confuse you . . . IMO batteries is batteries. :D A good approach would be to use the Perko battery switch with "Off-1-2-Both" positions. They sell them here on iBoats :thumb: That should take the guesswork out of wiring the batteries up, etc. . . ...

    Riser block off - closed cooling

    I just replaced the gaskets on my 7.4L w/ closed cooling. Merc does not have the stainless steel block-off plate, as they maintain that the new gasket (with internal SS film layer) serves the purpose. Barr still sells the stainless steel plate. These are the parts I used for each manifold (2...

    Is there a way to force New Members to fill in more Profile info?

    All too often we see new members join up, post a question or issue. . . Folks then try to help them, and often refer to their member profile for background information, like where they are located (country/state) what type of boats the have or previously owned, etc. Yet many of the new members...

    Exhaust Manifold / Elbow Gasket Replacement

    The joint between the exhaust manifold and elbows on my Mercruisers have been showing some rust over the past couple of years. So, I had a gasket replacement on my pre-season maintenance list for this year. Today was the day to start into it. I should mention that I have twin...

    Bravoitis Fix . . .

    Thanks for your guidance on this. :thumb: Yes, soapy water. Initially, I had been using the soap on the tube and rubber insert. Just now, I also used soap on the rubber hose itself, as it fits into a tight channel in the transom assembly. I found that I needed to get the position of the...

    Bravoitis Fix . . .

    As far as converting to thru-hull water pick-ups . . . If I went that route (eventually), I would like to get the positioning as close to the transom as possible (maybe within a couple feet) as we often 'catch some air' when out in the bay, as per the picture below. So, I would not want to be...

    Universal Warning Label . . .

    I got this as one of the 'extra' labels on an outboard decal kit . . . Rather than the plethora of specific warning labels, I thought it would be quite appropriate for a variety of machines and equipment . . . :D :D :D

    Bravoitis Fix . . .

    Cutting the hose and pounding out the insert from the outside in worked great :thumb: Here are a few pix Cutting the hose to expose the insert . . . I broke the insert up with a screw driver and a bit of pounding. After a bit of persuasion the hose came out. This one is the port side, you...

    Bravoitis Fix . . .

    As follow up to my over heating thread from last year (an issue which seems to be resolved), I did discover the beginning stages of Bravoitis on my Port outdrive. So, I planned on doing the Bravoitis fix on both drives as a preemptive measure. Fast-forward to now . . . the company that I work...

    Got an IR Camera . . .

    I've been itching for Spring to arrive so that the temps would start going up and I could do some decent 'testing/surveying' of my boat with the IR camera. Well today was a pretty good day, cold over night and sunny in the morning to start to warm things up. I went all through my boat looking...

    Do I need to prime outdrive prior to applying antifouling paint

    After you finish painting the outdrive, make sure to install a fresh set of aluminum anodes. You will go through them in 6 months.

    5.7 Mercruiser convertion to CCS, stainless risers also?

    I had to Google around the Internet to find the acid flush information . . . pieces here and there, mostly on auto restoration and hotrodder sites. A member here had recommended a radiator flush product, and that led me on a search about cooling system flushing. It seems that oxalic acid (wood...

    Pages not fully loading . . .

    The forum seems a bit broken this morning. The pages are not loading fully and therefore the editing features (formatting, attachments, etc.) do not seem to work. I have tried several browsers with the same result. (Mac OS X if that matters)

    Bought a 1998 Sea Ray Sundancer 270 wide beam with rot...

    Drew, In the drawings that you got from SeaRay, it shows a panel that can be removed from the aft bulkhead (i.e. the back wall of the aft berth). It seems that the removable panel is there to provide the clearance needed to lift the tank up over the engine mount stringers, etc. In order to...

    DIY Outboard Stand w/ Pictures

    OK, first use of the stand . . . I got a fairly large tub and propped it up on some blocks. Seems to work out well. With the casters, if I put the engine in forward it moves the stand a bit forward :D

    Mercury 7.5 HP Motor Refresh (1969 model year)

    I ran the engine again and set the idle speed down a bit. I got the in gear speed to be in the 700 RPM range, but it basically varied from 600-800. I had to tweak the fuel mixture to get the engine to stay running at that speed, but it does stay running consistently. So, looks like it is all...
