Searider 5.4

I think the engine you are looking at is 188kgs I don't think you'll get much comfort from that as its going to be arse heavy and tend to porpoise.
Avon have quoted around 340lbs (155kg) max transom weight for the 5.4 so the etec with it's alledged better running cost and better throttle response (have I been duped by Evinrude blurb) seemed to be a better choice than any 80ish 4 stoke. Agree the Merc is overweight but we have all seen bigger and heavier lumps on the back of Seariders before now. (Honda 90 4s, twin Honda 40 4s, Merc 150 2s.....seriously!) Has anyone had practical experience with these heavyweights? Suzuki sounds promising but I'm very firmly in the second hand market and the choice is limited.

To be honest my 2001 carb mercury 4 stroke is faster than my other sr5.4 with a yammie 80hp, Tohatsu 90hp (2 smokes) and the twin 40's that came off it before.
Plus you will save half on fuel and gain on speed! Hope that helps

I thought the Merc 75 & 80 4s were pratically the same weight at 180kg
What HP is your 2001 Merc, sounds impressive.
Oh and I have moulded a nice big bow locker and moved the console up a tad just in case.

What about the new 70hp Yammi 4 stroke ? Same weight as the 90hp 2 stroke !
Would be my favorite outboard apart of the 90hp Suzuki .

It's 177kg, 2001 75hp merc. There is the same engine on eBay, mariner 75hp £2850 might be worth a stab. Nice set up btw very impressed!!!

We bought an F70 and put it on Jaspers 5M and its a stunning engine. but I don't think the 5.4 deserves to be 20hp down on power that however is your call. The last three posters are welcome to come and try it out if they want

I also don't see the point in buying an engine that is so heavy you have to build a 35kg bow ballast in to make the boat behave like it would with a proper ( all right all right) a lighter weight engine on it. Nice bow locker and filler position by the way out of interest how much faster is the 4 stroke powered boat

You won't beat a 90 BETOL Yammie on an Avon but they are harder to get hold of nowadays.

Re Honda 90's etc is anybody going to put an underpowered and overweight lump on a boat and claim they didn't have a result, but I'd be very surprised if they did. The Honda 90 power was measured at the crank so that was a 200 + kilo engine knocking out 80 horsepower that emoticon is going to be the boat hitting the waves.

before I bought an Etec I'd be talking to independent service agents to see what they feel about them



Mr. Colcrete remarkable job on your Searider must be nice to have that kind of talent. I though my latest project Powerage was going to set a new standard but yours is very hard to beat.

I agree totally with what rogue wave says. He has extensive knowledge from what I can see on the sr5.4 and would be more than happy to put a yammie 90 on it. That is a cracking engine and I have used them for years.
I also agree that it is a ridiculous idea to have weight grp'd in the front (at least without sea trialing first) I purely did it through having the yammie 40's on it previously and it handled like a dog. They weighed 164kg. So the boat had been modified before slapping the 75 fat boy merc on it however it works a treat. I simply found the correct weight distribution from sandbags and fuel tank placement. I guess I'm lucky I get to spend over 1000hrs a year on this particular craft now, so have time to fiddle and get the bet result. I do have 3 other 5.4 and in a way I am lucky I can compare.
Very very impressed with your work and you simply have a stunning SR5.4 

Fitting out - Battery Switch

It's been a while but I am finally able to get outside and work on my Searider.
1st Job was to fit Dual battery changeover switch in the left side of the top half of the console
I used an Ice cream tub and some cardboard as a makeshift mould and made a simple glassfibre mounting box to fit inside the console and accessed from the outside by an inspection hatch.
Drilled 3 x 1" holes in the back for access to the terminals and 3 x 18mm cable entry holes in the bottom. It will all get Sikaflexed in place as well as the self tappers when I do the final fit.
(Yes Falcon I made the consoles as a joint project a friend of mine).
I also bolted on a charge isolator to the side of the box.
