MARINER 4hp 4T SAILMATE longshaft o/b (advice please)

[ferrispeterchris]

I have been offered one of these and wondered what (if anything) the Sailmate means. I came across an old post by Lakey which suggested a different (larger?) prop did I pick this up correctly? It will be going on a Hunter Europa. Thanks. I have also been offered a Yamaha 4hp 4t which would be lighter?

Usually means a finer pitch prop so it can transfer all its power at a low boat speed. Sometimes means regulated/rectified battery charging output as well, but less likely on a 4hp.

It's still possible it may have a charging coil; my Mariner 4 & 5 do.

IF this is the two stroke ? Beware the gearshift on the 4hp, the rubbery plastic shift tends to jam or at least go very stiff in the alloy housing, fixable with a drilled oil lube hole and plastic tape cover - inside the cowling.

Either should be ideal for a Europa, four strokes are a bit heavy though - and I know Oliver Lee designs don't like weight aft - I'd prefer a well maintained 2 stroke Yam / Mariner 4 if you could get one; a matter of personal choice.

As above

Usually sail versions are longshaft which enables you to mount them deeper . In some case the exhaust outlet may be modified to prevent an increase in the back pressure

Usually they have finer pitch props, making them more suitable for slower displacement hulls, and may be a larger diameter or have larger area blades.

Battery charging as standard as well possibly although that's not a great deal of use if you mostly sail! Low output charging coils on small engines may not be regulated although there seems to be an increasing tendency towards regulated ones now.

I'd have thought some form of battery charging handy unless the OP only daysails on a lake ?

Europa's are as capable of going far as any 30' +, as David Blagden demonstrated transatlantic with his earlier H19 ( from which the Europa was developed ).

There's not much space to put a solar panel on a Europa, and total loss batteries requiring taking home to charge are a serious pain.

A 2012 Marina 5HP saildrive came with my recent boat purchase and just to let you know there is nothing in the manual about the charging system so you will need to ask a dealer for info on output etc. Just had to do it so thats how I know. Gives out 3-4 amps/watts not sure which now but that's in the higher rev range when you are using it, it weighs 25KG and the prop as said gives you more oomph in forward and reverse...

I will probably sell my hardly used Yamaha 6HP, very smooth, quiet twin cylinder for sale. Lovely engine but it weighs 40KG
