I am looking for a new engine for my ex coastguard 5.4 sea rider. A few considerations before I do anything though!
I have trawled through the forum for info & trying to make sure that a: I get the right power to weight ratio/fuel economy & b: that I don't overload my trailer & get a fine/points on my driving licence.
The most popular choice seems to be the Yam 90. I'm not too bothered about top speed & it's unlikely it will be used much further than a few miles off shore. Did I mention fair-weather too. I bought the boat from a sea cadet unit who used it on the london end of the Thames with a 40hp and it performed well, the sea I know will need a bit more for me & my sandwiches. In my mind I had 60-70hp to keep the weight down.
I have an indespension (un-breaked) roller coaster trailer that will take a max of 750-ish kgs. I'm going to call indespension with the serial number to be exact on tuesday as the VIN plate is a tad confusing. No problem towing the weight as I have a LWB Defender. I just want to make sure that the boat + engine + fuel + trailer is fully legal. Might be a trailer replacement but I hope not.
I also intend to weigh the boat & trailer at my local weigh bridge ASAP, again to be exact.
I found the info in the photo of 5.4 weights and have included the web link to them. Can anyone tell me if these figures plus any engine etc are accurate & if my proposed engine choice is sensible?
