Hi,
For that budget I assume your looking new, and thereís probably nothing between the big 5 makes in terms of quality and reliability.
However, for me there are two which stand out from the crowd. The Suzuki DF20 and new Tohatsu MFS20E. Both are considerably lighter at 44 and 43kg and both have the benefit of EFI.

Chipko sums it up perfectly really. Any of the major 5 are good outboards but the two Chipko advises are the same as I'd choose between now. The reason being their lighter weights compared to others and as important to me... the move to EFI over carb.

In 2016 when I bought my Suzuki 20EFI new it was the lightest and only EFI in its HP class. I decided if I was going to move from decades of decent 2-strokes to a 4-stroke I'd like to get the latest tech.

Now though the Tohatsu has matched the Suzuki and if I were buying now I'd be looking hard at the merits of that vs Suzuki.

It seems currently the Tohatsu and Suzuki are a little over £2400 discounted. The Mariner is the only one usually getting within your stated budget.

Beyond that look at the features of all inc gearchange posns relative to tiller, ease of carrying (handles etc). Also the proximity of a dealer for a particular make may be important. Don't forget the varying servicing needs to keep up the 5yrs+ warranty.

As a matter of interest getting to the less than perfect dealer for yearly servicing has made me take the decision to forget the warranty after year one and self service.

Couple more small points come to mind that might/might not matter to you...

Some 20s are supplied with a 25l tank and others a 12l. Mine came with a 12l which was too small so it cost me another £50+ for a 25l tank.

4-strokes have differing ways you can lay them down to avoid sump oil getting the wrong places according to make. Mine is on the side and only one specific side.

Personally I wouldnt take a efi over a carb engine at that size for any reason.
It's probably on a small boat and the risk of fuel contamination is fairly high and fitting extra filtration may be impractical
I'd take the simplicity and fixability of a carb engine every time at that size

>>>the risk of fuel contamination is fairly high

Why so on a small boat with lift out tank? It is so easy to exclude contamination in this circumstance... as opposed to larger craft with integral tanks where there is a greater potential to build up gunge and debris over the years which is an absolute pain to remove.

If you are worried about contamination a see through casing inline filter can be fitted anywhere along the fuel line that suits.

Itís certainly possible to get water in tanks from a stuff or even a lot of spray/rain etc. The bleed screw is designed to ďsuckĒ air in and will suck water in if itís there. Boats left on moorings or launched through surf are also vulnerable. Iíve had sand in mine - probably from kids putting feet in tank and it then getting in when filling up. Old metal tanks used to suffer from condensation, and rust issues. And of course tanks get left over winter to go stale...

Most of those issues affect bigger boats too, but you can mount the vent above the flooded water line and better protected from rain and usually much harder to contaminate the filler with sandy feet. But I think Kenís point is on a 5+m boat you can easily fit proper water separators and filters, on a small boat that is harder to do (but not impossible).

for a 20 hp I would be looking at the parson engines I have had 2 and both have been faultless people won't look at them because of big brand snobbery but I was seriously impressed

Well fair points to a degree Poly but many of those circumstances I would regard as avoidable by care in use**.

In any case... to take my Suzuki... extra filtration is possibly over the top as it has the in-tank filter, the initial service replaceable fuel filter with water drain plus two further filters in the HP pump before fuel gets to the injectors.

**For example I avoid spray getting anywhere near the tank vent by siting the tank under the Mrs sitting on the seat above so she absorbs all that. And re stored fuel... now we've gone 4-stroke at the end of each outing I sell the unused fuel to my daughter for her car so we don't store any fuel.

But having said all that if any purchaser feels happier with a carb then that's the way to go. For me though the benefit of precisely measured fuel and the loss of the carb massively outweighs any tiny chance an injector might get contaminated.
