    Windshield WiperMotor replacement

    Hi... I have a 2001 Wellcraft Martinique 3300, and one of my windshield wiper motors is not able to move my pantograph wiper. I can hear it run, but it won't move the wiper. When I take the Wiper arm off the motor seems to run ok. The boat uses separate self parking motors for the port and...

    Hi... I'm hoping that someone can give me some advise on how I might be able to repair or replace a piece of moulding that trims the companionway to the headliner in my 2001 Wellcraft Martinique 3300. I had to remove it to get above the headliner to repair a windshield wiper issue, and when...

    Air Horns failing intermittently

    I have electric air horns on my boat, and maybe 50% of the time they do not work. I can hear the electric pump operating, but no sound from the horn. Other times no problems. I thought that it might have been inbound air pressure into the horn counteracting the force of the air from the pump...

    Looking for some suggeestions. My motors are 1990 7.4 Bravos with FWC. On one motor, I lose antifreeze over the course of a couple hours of running time. It not too much, but even a pint or 2 low causes the the temp gauge to climb a little... maybe to 190 degees... I cannot see any visable...

    Can anyone tell me approximately how far out from fully seated the slow speed mixture control should be set to as a base line to get the motor started? I just had to clean out my carb and took it all apart, and I took a sample of where it was by counting the turns in to fully seated, and set it...

    another fuel filter question

    Can anyone tell me what the micron rating of this fuel filter is? It is a MerCruiser part number and meant for an in-line filter for Big-blocks as I understand it... (can permit the fuel flow volume needed by the big blocks) http://www.go2marine.com/product.do?no=159026F

    Fuel Flow meters on 7.4L

    Vortec conversion on a big block

    On another post, http://forums.iboats.com/showthread.php?t=248599, it was mentioned that you can get more power by replacing the heads on a 350 block with the Vortec head and intake... Can this or something similar also be done on a big block, 1990 7.4L (MerCruiser) In other words did they make...

    Heart Interface Inverter/Charger

    I have a 1000 Watt Heart Inverter on my boat and for the past few years it has worked reasonably well.. This weekend I spend 5 days on the hook and it just did not seem to survive very long before it required recharging. I have a 1000W generator that I think was having some issues on top of...
