!998 4100 scr

[wendellbee]

I've set my sights on a 1998 4100 with Cummins 6TBA's @ 1050 hrs. after passing on a 3700 scr that needed new stringers, cabin floor, and motors. I will be getting the 4100 surveyed and will have a diesel mechanic look at the engines. Is there anything that i should be looking out for on these boats? any idea what the fuel burn is at cruise? I have a long ride home if i purchase it.
Upon initial inspection the only issues I noticed were:
- no drain plug for bilge
- rear cabin has hatch in floor (to access shower sump). the screws/nails that
attach one side of the lip around the opening to support the hatch came loose. did not feel or see any wood rot underneath.
- generator runs but does not produce any power (not too concerned with this).

Best wishes and let us know if you get it.

Maxum made the cleats for those sole hatches by screwing from the top. So when you step on the hatch, you're entire weight is suspended form the screw threads. It's a poor (lazy) design. What I did is remove one screw, drill through both the sole and the cleat, then through bolt with 316SS bolts, washers, lock nuts and a counter-sunk flat head bolt. 8 total (2 for each side).

A drain plug can be installed. I'd hog out some of the transom wood, and back fill it with thickened epoxy before installing the through hull.

Marine generators are all problematic.

fuel burn...LOL!!! Well, there's always golf

i know fuel burn is a joke. just want to estimate how far i'll get when heading home before needing to refuel. good idea of putting bots thru the floor. definitely will do that as one of the fall projects if it passes the survey. thx

Thanks for the chart. Not a sipper but way better than the 460’s I had in my Chris craft crown 340. Until I’m confidant with what the fuel gauges show, I’ll use worse case numbers on the maiden voyage
