So....
I?m sitting here with a glass of wine after an artic day out on the jet ski....and thinking about the spark plugs I?ve went through during the run in period with heavy oil to fuel ratio....and a question came into my head.
Can spark plugs be Ultra sonically cleaned ?
Perhaps this is...
Hi
I have the chance of a cheap winter project...
Wee speedboat with what I think is a late 80?s DT65 2 stroke.
The chap is selling it cheap and is not a technical guy but tells me the power trim needs bleeding. He claims or seems to think the vent screw is only accessible by removing the...
Whilst firing some anti freeze in the engine today and checking for proof on the side of the block, I noticed the port fwd engine mount but was not only loose, but half way up the thread with the spring washer hanging in the breeze !
Slightly worried now...guess I need to check the alignment ??
Guys
The manual might be able to tell me, but it?s not to hand.
What size (AH and CCA) battery are most using to start their small block v8?s ? Mine seems very small in size, but seems to do the job. It?s a 85ah and can?t remember the CCA, but it is purely a starting battery.
Ok...so it?s late over the pond here in the UK and I?ve had a few beers. Added to this, I?d imagine there is a simple explanation for my question and I realise I could probably find the answer in a more sober state, but hopefully someone can answer this quickly...
At cruising speeds I have a...
Can someone please tell me what witchcraft is at work with regards to the Merc blue drain plugs ?
I have one on the T Stat. Every spring I tighten it just less than hand tight....and every winter it magically seems to have accumulated a torque tighten figure of unimaginable quantity. Enevitably...
Guys, if you have 5 mins, check out some of the records broken (national and world) at Lake coniston this week.
The mighty Silverline smashed the world record for immersed propeller class
An F4 boat managed 81mph with a 60hp !
The world record was also broken for a Rib too.
Amazing stuff over...
Ok guys...looking for some back up here...
On a uk forum..a totally inexperienced fellow asked advice on his boat. He stated that his inboard displacement shaft drive boat had 400hrs on her and he had no record of anyone changing the shaft packing. He hadn't done it either in his owner ship.
He...
Ok...on a light hearted note...whilst these new HO big horse power engines look great and I'm a big fan of 2 strokes....
I don't get the whole 150hp HO (that actually produces 200hp), the 200hp HO (that actually produces 250hp) and the 250hp HO (that actually produces 300hp).
Why ? Why not just...
Hi guys
In general, whether it be Mercury, yamaha, jet ski or other...and given the oil injection system is still in use..
What should I mix the tank with for the top end break in procedure ?
Was thinking for starters, a tank full @60l at 100/1 or maybe less ? Then follow the usual breaking up...
Crazy how much the boat has slowed down since her highly polished launch early season. Used to Rev to 5000rpm or just over ! Refuse to antifoul her. Look at the colour of the hull and the growth on it !
Ok, so on my constant search for prop perfection, I e decided to take the plunge and order an enertia prop.
Is it possible to have too many props ? Should I trade in the laser 2 ? Can't bare the thought of it.
Bit of history...
Not had it long..was running great first few times. 112kph on the speedo (58mph real speed gps)
Next few times out started surging at top end. Would give the full beans sometimes and sometimes hold back and only do 90kph on speedo and dropped about 400 rpm.
Next and time...
Jeez...after reading the updated bulletin from Merc about laying up an MPI.....really ? That much 2 stroke oil ? Not sure I'll bother with this one !
Surely I'd be better just sticking a small amount down the plug holes and turning it over (without start) a few times ? Not sure I fancy that...
Ok so....
After recently just getting back into jet ski...bit of a dilemma !
Ski is a 2002 GP800r and I'm aware that any good TC-W3 oil will do, but prefer to use the yamalube. Problem is that after filling the tank with the synthetic 2-W oil, a jet ski yam expert has now advised against using...
Hopefully I'm allowed to keep this post in this section, as it is a boat related topic...and the PWC section isn't that well read, by the looks.
I have a 2002 Yamaha wave runner. Old 2 stroke type with raw cooling.
Having had a seadoo years ago (yuch), when towing I had to pinch the water...
So I'm after an enertia prop, but they are almost unheard of here in the uk. I can get the Merc dealer to order one in, but would cost around ?600 sterling.
If any of you guys know of a mint condition 19" one in the US, let me know via PM
Thanks.
Hi
Just recently picked up a great wee yam GP800r for little money. I haven't had a ski for a good number of years and just wondering if others with the same model have tested or figures the actual speed achieved.
It has a riva ride plate and god knows what impeller (haven't looked).
With...
Wee shot on the Loch earlier. Lovely when the weather is right. Camera boat is an old school Fletcher Arrowbeau 17 with the big monster yam 225 2 stroke and 25" cleaver. Both running around 65/66 mph GPS
