Phil,

Don't use epoxy on mahogany, it'll darken it to almost black... Use an oil base sanding sealer then a good varnish.

Wow Ol' Buddy, I thought you might be thinking of something like a Meyer's Manix type one piece body... The Floppers used fiberglass look a like bodies of street cars like the Camero, Mustang, & even VW Bugs. That's gonna' be some real complex molding, probably of multiple parts and then the parts a...

Looks like I'm gonna' survive... Some nerve damage, which will, theroretically, re-generate. Wound healing well, all ten fingers work, some numbness to the heal of thumb & a little clumbsy rotating the wrist.

If your thru hull fitting is less than the size of the pump discharge then you won't be pumping to the full capacity...

Br,

CaptPatrick

Phil, Never heard of that mod before... If the pumps were Rules, there's no need or advantage. The Rule is a centrifigul pump that is vertually open and self draining when not running. The only problem I ever had with larger boats & Rules stemmed from the length of the discharge hose. Lengths can ea...

Tom,

As long as the connections and wiring is marine grade & installed as outlined above, there is little need to do a final coating. But if you want to further protect the mechanical connections, use Liquid Electric Tape

Br,

CaptPatrick

Phil, Always use marine grade tinned wire for boat applications. For bonding from the copper strip to the item, use 8 ga green insulation wire & try not to exceed 1' in length between the copper strip and the item. Crimp and heat shrink is fine, but use the heat shrink that has the adhesive interior...

John, One 6" round port gives you 28 1/4 sq in of free opening. Two 4" round ports is 25 1/8 sq in of free opening. That's 3 1/8 sq in less than the single 6" port, but should be close enough... Doubt that you'll find a ready made fibergalss connector to fill your needs, so you'll probably have have...

CaptPatrick

Lou, The quick way to determine which tank you have is by the construction. The old 173 gallon tank is capped with a flange all the way around the top perimiter. The newer 223 gallon tank is a "shoe box" construction, so has no flange. A few of the newer size tanks, late 71s, were also shoe box cons...

Scott,

The principle difference is that the higher the number, the more corrosive resistant the alloy is. The lower the number, the alloy is a little less brittle. I prefer AQ22. Diesel HP at or below 240 can remain 1 1/4", 250 - 330 needs 1 1/2", 250 - 440 needs 1 3/4".

Rawleigh,

That's Lenco Marine, (Trolling Tabs), but unless the boat were haulled between uses, (in/out storage or davit), maintenance could be a nightmare.

Br,

CaptPatrick

Lore, 1.5KT, (1.7MPH, 2.8KPH), is pretty slow, so it won't take much thrust to move your B28 at that speed... An alternative thought would to use an electric trolling motor. Minnkota make several salt water versions that could possibly do the job. They even make an electric outboard model that would...

Ian, Different amounts of resin are required to wet out different forms of fiberglass. For example, one gallon of resin will wet out approximately the following amounts of fiberglass: 40 square feet of 8 to 10 oz. cloth 50 square feet of Â¾ oz. mat 30 square feet of 1Â½ oz. mat 35 square feet of 24 ...

Phil, Placing buss bars in convenient locations is good practice, rather than tons of heavy wire to individual items. For buss bars in damp areas it would be a good idea to intall them inside a plastic box. These boses can be had through Radio Shack in various sizes. Use rubber grommets for the wire...

Since I totally encapsilate the engine bed sisters with epoxy and fiberglass, then cap with channel, I just use plain old pine 2x4s milled to dimension & laminated edge to edge.

Merlin, A high pitched whine or squeek/squeel coming from the running gear is almost always a bad cutlass bearing or something fouled up inside of it. This is assuming that the sound is not coming from under the engine box. While a cutlass bearing may look OK from the outside, there could be a few s...

Ian, Corecell will do fine. I used Klegecell on "Buddy Boy", pretty much the same stuff, just different manufacturer. In order to get a true structural composite sandwich, glass over the exposed surface, (after bonding in the foam), with a layer of 1208 biaxle cloth. Without the layer of fiberglass ...

Guy, First thought off the top of my head is where you'll get your boat painted. Jarrett Bay in Moorehead has done some real crappy paint jobs on boats other that their own new boats...

Nic, The long standing rule of thumb for air capacity to a diesel engine is 1/2 sq in of free air flow per 1 hp. (300hp x .5 sq in = 150 sq in) Free air being defined as air that can freely flow without restriction. That's the formula that I used for both of my side induction styles. The formula was...
