Wouldn't it be more cost effective to sell the manual trim engine and buy a power trim engine. Probably not a lot different in money terms than adding trim tabs and should solve you problem
Make the boat a totally different animal

Got the engine very cheap and did a lot of restoring work to it, so Id be very reluctant to part with it. Especially that yam or honda 50s with PTT arent exactly cheap.

A bit outside the box........but, instead of a bag of sand how about a ballast tank "ski-boat" style and some pumping arrangement to fill and empty it?

Would be an interesting idea, but after Pikey Daves post I decided to bite the bullet and bought a used PTT unit that should fit my engine from the States. If it works and fits it would be perfect, if not one can still sell it over here.

So for now, no more trim tabs. Will think about them once PTT project is done and i have some more boat money.

Once my trim unit has arrived Ill report back.

I understand about not wanting to part with the engine you know but how about buying a running power trim engine and swapping the bits over then reselling it as a none power trim engine or even breaking it for spares
Yours looks like a 2 cylinder 50? If it is then at that age even a power trim engine is probably worth not much more than your being qouted for a used power trim unit
The other thing to consider is has the foam in the rear buoyancy module under the deck become saturated and weighing the stern down

+1 cracking idea. You could integrate it into the flux capacitor circuit & control it via the di-lithium matrix.

That's just silly.

If it was me, I'd glass a rail into the deck and rig a pulley system to run a block of lead fore and aft. You could use a sailing winch. Not sure where I'd store the handle when not in use. It's a can of worms.

You just covering up the issue, which is 40kgs of fuel/extra weight on the transom/stern, the Hulk tanks fit nicely under that consol, 22L if i remember and if you need to carry an extra fuel capacity then add a Hulk tank 12L or the 22L up front as shown.
Thus leaving your stern light as it should be especially with out PTT.
SR4 's are small slim boats and don't take kindly stacking weight up on its arse!

If you want it to handle better, your going to have to move the fuel or counteract a 40kg problem dude

That would be almost as much over the top as fitting trim tabs to a 4 mtr boat.
A simple switch or lever like Mastercraft, Ski Nautique, Malibu or the RLNI use would do fine.

Yep, it's the 2 cyl 55 HP engine.

afaik any PTT from a Yamaha up to 90 HP from the 90's would fit, those are the three cylinder 2-Stroke Autolube engines and they don't go cheap, they are in fact quite hard to get for a reasonable price(It's the reason I run the 2-Cyl, because it cost a third of the same HP model with 3-cylinders, PTT and Autolube.)

As much as I'd love to move the fuel tank foreward, it would either cost me range(which I really can't go without) or deck space(As the console would have to move back which would involve major work, which is not an option either)
