Just thought I would mention this...I've been using Mtroniks Speedo's in my racing buggies for a good ten years. Whilst looking for some cheap robot speedo's I thought I'd have a look at their website. I've noticed they do a range of boat speedo's at the 10-30 amp mark that look in line with Electronizes etc. I'm gonna order a couple and will let you know how it goes. Please have a look at the link below:
