    new "whirring" noise

    I recently had my 1998 4.3 liter, mercury alpha outdrive worked on. The engine was a complete rebuild and the impeller and bellows in the outdrive were replaced. During the first 10 hours of running there was nothing unusual, but during the last run there is a whirring noise, like a small...

    copper fuel pipe?

    I just pulled up Title 46 sec. 56.50-70 of the Code of Federal Regulations and it states, "(a) Material. (1) Fuel supply piping to the engines shall be of seamless drawn annealed copper pipe or tubing, nickel copper, or copper nickel pip or tubing meeting the requirements of subpart 56.60"...

    flaring tool

    I had to bend the stainless steel fuel line from the fuel pump to the carborator in order to make room for a closed cooling system. That left the fuel line a bit too long and I cut off the flared tip. My cheap flaring tool will not flar steel. Who makes a good one that will flar steel, and is...

    Location of San Juan Engineering

    Does anyone have the phone number or location of San Juan Engineering? I installed one of their half systems on a Mercury 4.3 lt. with one piece manifolds. I'm now replacing the maifolds with two piece manifold riser set up and need to know what additional parts I need to make it a full...

    locked up 4.3

    Mystery. Two weeks ago I checked the compression on my motor and it was bad (90 to 165 lbs). The mechanic just today pulled the engine and said it was locked up and couldn't even get the crank to turn with the plugs out. It goes into the machinist next week for a rebuild anyway, but my...

    Pro's: What should I have done and how much should I pay?

    I've got a 1998 Starcraft Islander with a carborated 4.3 lt. 190 HP with a Mercury alpha I. Other than change the oil I've done nothing. The boat has been used primarily on fresh water but has been on salt water for a month each year in 1998, 2002, 2003. I know that the compression is off...

    Where are the Mercury Diesels?

    I noticed on the web that Mercury and Cummins diesel have teamed up to make diesel out drives. Except for a 20 foot Trophy I haven't seen any boats on the market. I would also like to possibly repower with a Cummins diesel--so does anybody know who's building boats with these diesels or what...

    diesel replacement

    I've got a 2,200 pound 22 foot Starcraft Islander with a 4.3 liter 185 HP. It works OK, except for dieseling, but am thinking of replacing it with the cummins 1.7 turbo diesel in order to get the range to go after tuna. I read a popular mechanics article that showed the 1.7 got better than 6...

    Mercathode Needed?

    I left my 1998 aluminum Starcraft islander with a Mercury Alpha 1 outdrive in saltwater for two weeks last summer. The zinc plates on the outdrive corroded significantly, but the one on the hull is like new. The hull also showed no damage. I'm going to leave the boat in salt water about a...

    Need Advice on Fresh Water Cooling

    After reading another thread you guys have convinced me to install a closed cooling system. I would like to install a full system on a 1998 GM 4.3 liter (model 4211015LS) with an alpha 1 outdrive. I need advice on best brands/models and if this is something a shade tree mechanic like myself...

    diseling 4.3

    I'm running a 1998 22' aluminum Starcraft with a 4.3 liter engine, alpha 1 outdrive and 22 pitch prop on the ocean. Unlike some of the other posts on diseling mine does NOT disel if I've come off of a plane. Instead it disels when the ocean is rough and I have to trim the motor all the way...
