perfect upgrade, it fit my project boat
By ROBERTH from SEBEWAING, MI

Verified Purchase

I used this to upgrade my 1974 Whitewater Jet drive center console 22'pug nose. This boat has great lines and has a 302 ford small block. It was used in a salt water situation and developed many points of breakdown in the electrical system. So it was start from scratch to update every connection. It didn't help that it set out in the weather and was loaded with pine cones and needles from the great north west. It has been a 5 year make over and is drawing close to completion thanks to the new fuse block. It gives direction and organization toward the end of the project.

Bottom Line Yes, I would recommend to a friend

Very nice easy to install unit
By Larry from Spring grove ,Pa

Replaced old tube style fuse block with blade terminals with this unit . Very nice unit i got it with the cover. Cover is nice and locks in place so it won't fall off. All screw terminals on it positive on one side negative on the other. Also includes labels with it they are blank to write your own.

Bottom Line Yes, I would recommend to a friend

Excellent fuse block
By Capt. Kidd from Port Hadlock, WA

This Bluesea fuse block is an outstanding piece of gear. It has a very small footprint yet room for 12 circuits. The blade type fuses are a good choice because they are rugged, small and easy to get. A quality unit.

Bottom Line Yes, I would recommend to a friend
