100hp at the prop x 2 is 200hp it'doesn't disappear
What you do gain is the extra drag of another leg in the water, going from posts on the topic it's estimated at a few percent efficiency loss
Also extra weight as generally twins will weigh more then the same hp as a single engine
And the addition of extra oil res cables steering fuel lines etc
The benefits are substantial though only if hooked up completely independent of each other
Ie own batteries and own fuel tanks
-
They handle some expansion but you can permanent wreck some tanks if left too long
The ability to seal the tank is so you don't slop fuel on yourself when you manhandle the tanks
Or get water in when you wash the boat
As stated above a permanently sealed tank would starve the engine of fuel after a few minutes of run time
-
You need to strip the case and before welding heat the whole casing
It's very easy to distort the case and bearing seals etc won't fit any more
More a specialists job both to weld and put it all back together
The sludge may just be unburnt 2 stroke oil, check your gear box oil what colour is that ?

Too top up a deep cycle within a few hours of full sun you would need about 20 m2 of solar panels
Those little sub $100 jobs will do nothing to a discharged battery
Best bet is two batteries a cranking batt just for starting
And a deep cycle for running accessories that can also be switched too if the main battery fails
I've just done this and the cost was about $1-150 in materials plus $400 for the deep cycle
Never switch between batteries while the engine is running as it can bugger the charging circuits
And don't run the switch on "both" unless both batteries are identical in size capacity and type

Doesn't explain why they have breather caps in the first place.
liquids expand when heated and contract when cooled
leave it closed and put a tote tank out in the sun, even if empty it will expand and distort

Hello wise people of Fishraider.
I am looking at purchasing a 4.5m half cabin that has an old Johnson on the back of it. The seller says it idles fine both in and out of the water but dies as soon as he goes to move off. I am going to have a look at it on the weekend so will find out more then. What could be causing this. I was thinking old fuel as I know it hasn't had much use, or a split fuel line that is drawning in air. What other things could it be?
Thanks in advance

flooding carbs
failed power packs
if you hold the choke in does it keep running ?
id take a old engine with 1000 hours on it but regularly serviced over one thats sat for years and never been looked at
they still need servicing once a year even if not being used
gear box bolts can become seized, rubber can perish that normally would be ok as it would be smeared with grease every service
offer him trailer hull and fitout value only and factor in a repower

One word off advice if your going to have a go yourself
Buy the best dust mask you can afford, paper masks are not acceptable from any oh&s stand point
Double can respirator at minimum
-
i use standard 100lb fishing braid as my downrigger line and 2-3 knots is ok u can by a trolling plate that covers the prop this will slow your boat right down to perfect speed but u need to drill holes similar to a hydrofoils
i troll at 1 knot, but with the engine just in gear it does 1.5 so i just have a cheap sea anchor i throw out the back cuts down by .5 of a knot
-
looking good
A neighbour has done a haines 445 resoration similar to this, he went a 70hp 4 stroke yamaha
he said this is a bit too much grunt and a 60 would be ideal

Just wondering if anybody knows where i can get bearings for a single axle (13'' wheels) trailcraft trailer as i want to get a spare set i havent really looked around yet, so i thought id just ask here first, im pretty sure theres a few trailcraft owners out there.
Cheers in advance Steve.
take the bearings out give them a clean then go to cbc bearings
you will get quality bearings for a little more
at a minimum get timken

If your club sport is manual it's exactly 1.5 tonne less then my Mazda bt-50 can tow
Hp ain't everything

Don't run engines dry you an seriously bugger some of the newer ones
And with older ones with alloy fuel bowls you wil get oxidisaton of the ally
Also if you have oil injection you will just fill the bowls with oil making it a bastard to start next time
-
abu1600c simple and quality baitcaster can cast down to 3-4gms
-
also keep it dry as possible, on grass with a tarp over it doesn't help
i kept mine in the garage but then realised the clothes drier was pumping moist air into the room and causing issues

I would be very happy with a good oldy runabout for 5ish if its possible. Don't mind an ugly old girl if it's reliable and in good nick.
My mates first runabout was a glass junker that literally looked ready for the dump, it lasted three years, was out every week and we caught every species in every area of Sydney, great memories!
Any specific makes to look out for?
Half cabin or cuddy would be great for overnighters in summer but is that achievable in this price range?
Appreciate the advice.
break it down into 4 parts
hull
trailer
outboard
electronics and fitout
the outboard is the most expensive part of all of it
a 4.5m halfcabin will need 50-70hp a good outboard say 6-10 years old
outboard 2-3.5k
trailer 800-1.5k
that leaves you 1k for the hull value
buy a 12-13ft tinny with a 15-25hp engine for 3.5k and have 1.5 to fix it up and fit it with some luxuries
an example i bought a 5m cuddy cab so no cabin in alluminium with a 70hp at xmas for 9k its a 1996 model so 16 years old
for 5k you aint going to get anything id take my family out in

Good for underpowered boats or boats with too much weight at the rear ie two guys battery fuel tank with a tiller steer
Can be disastrous boat in a big following sea,
Gives the wave more leverage on the rear of the boat
I wouldn't put one on a offshore boat, I'd fix the true issue to why your boats not performing
-
the proper way is too drill oversized holes
fill the holes with a resin talc or microbead mix
smear the bolts with Vaseline and then place them in their final resting place in the holes
when the resin mix dries the Vaseline stops the bolts getting stcuk and forms a thread
this will stop any water ingress into the core of the transom

Plus 2 for the Entrance
my prop looks too pretty to go to the entrance lol

Could always try to buddy up with another boat and share information on the day via mobile etc
Someone finds fish the other let's em know vice versa
-
And in the end you have a boat that will be labeled home made in the rego papers
Resale value will be low, if you pick a company to weld it for you
Pick someone with a reputation in the boat industry so you can move it on easier

how hard is it to weld aluminum with the correct mig welder? ive welded with a mig welder a few years ago i welded half a car together that stayed together when my sister done 50kph over a speed hump without thinking
if you saw the quality of the welds on my 385 explorer not hard at all
a decent built and fitted out plate boat will cost more then a extruded jobbie from the major players
-
There's a tonne of difference between a pressed jobbie from telwater and a well designed plate boat like a jb or others
Generally for the same length you get more hull depth and more v along the hull and a lot stronger built with more features
My mates 5.2m Joshua boats center console shits all over tinnies the same length for ride and deck space

What benefit do you think your getting from 98
Apartfrom the detergents and short shelf life additives they include to get the extra hp
