what is this engine?

A Mariner 75 fourstroke on a boat which I wouldn't even trust for pootling round the harbour in.

I have the same boat and as Lencraft are out of business I am not sure how big an engine my boat will take (the pic is from their website which say max 75hp but is that a 4 or 2 stroke as the weight will surely be the most important factor). I have a 55hp 2 stroke engine currently on it but am thinking about changing it in the next wee while and I was dissapoiinted in how fast the 55 went and it is not running as well as I would like.

So I suppose the real question is - how hevy is that engine and what are the options for a used engine like it? Would a DF40 suzuki be as crap as I would imagine on a 4.m rib? I would have thought a nice 60hp yam would be ideal - any other suggetions?

The engine in that picture weighs 175kg dry.

I used to have a 4.2m Zodiac Pro with a Suzuki DF50 on the back and that was very spritely 32knts top end. On a 4.8 40 would probably be fine but it won't set your hair on fire. A 60 would be excellent, Spartacus on here has a Ribcraft 4.8 with a Tohatsu 60 that he has fettled for a little more go I believe.

Depending on your local dealerships, at 175kg or under you have all the etecs, optimax, yamaha 2 and fourstroke. Pretty much everything really, as 175kg is only 20kg less than an etec of 200. Heavy old beast.

Might be best to check the plate on the transom of the hull. Failing that put on a 60, light tends to be best, and make sure the insurance company are happy.

All the best.

funny they are about the only boat maker that I can't find much bad stuff about on here! Whereas all otheres get a roasting every now and then! Liley just avolume issue in that there are so few Lencrafts around that they by percntages will have less problems show up on here!

Anyway I have it and really like it, it suited my budget and is all the boat I currently need. Just need a reliable engine for it and I ma sorted.

So if the 75hp 4 stroke Mariner in the brochure shot is 175kg does that mean any engine under that weight should be OK, i.e would an 80HP 2 stroke be OK if say 150kg?

[dubrus]

4 stroke mariners normally have white stickers on the side of the cowl saying 4 stroke-can't see that on that engine. i assume that is a 2 stroke motor which would make more sense due to the weight on that transom?



cheers

There should be a plate on the boat saying its maximum rated power and/or weight. Both can be important. If no weight stated by the manufacturer then they didn't consider it critical, but obviously use common sense. Its unlikely the transom will just fall off by putting a stupidly heavy engine on it - but it may well screw up the balance and handling.

So you've based your rather scathing assessment on some internet gossip or have you actually ever seen, inspected, driven a Lencraft? Do you apply the same approach to all brands which have even had an internet complaint about them? (I can point you to cracked transoms and tube delaminations at two BIG manufacturers who are generally well regarded (one close to the top end, one at the budget end) - neither have gained amazing reputations for outstanding after sales support - but i'd happily take either of their 4.8m models out in real seas. I've no personal experience of Lencraft, but whilst they may well not be the craft I would aspire to own I don't think I have seen enough to convince me to walk past a good deal because of the badge, or is this just the usual Ribnet "if its not my brand its crap" nonsense

If you look very closely at the front top of the engine cover, between the A-frame, there is a small dark area - this to me looks suspiciously like the access cover to an oil reservoir which would indicate it is a 2 stroker,

And thats all that matters
