  1. Cowlings can be deceiving in that way. I'm looking for a 200hp at the moment, prefer my Yamaha dealer but the product planners have made it difficult, their only XL shaft 200hp is the 2.8L I4, sure it'll make 200hp but you won't see the bulk of it without a lot of revs on board. Mercury on the other hand, 3.4L V6 and 4.6L V8 200hp options, say no more.
  2. I haven't seen it mythbusted before and I suppose it would vary between each manufacturer regardless. Evinrude actually used to state that besides the gear ratio, engines like the 115HO vs the standard 115 utilised the max 10% wiggle room they have in certified hp ratings, i.e. a 115 could technically legally produce 126hp, so most likened the 115HO as basically a 130. Mercury's 115 and 150 Pro XS models also run more rpm than their standard counterparts. While this enables you to play with lower pitch props without necessarily losing top end, all things being equal, raising the rev limiter by 300rpm you'd expect slightly more peak power. Mercury's R&D VP stated as much- “Horsepower is simply torque times rpm,” declares David Foulkes, Mercury vice president of product development. “As long as the torque curve is still climbing, if we add rpm, we get more power. And the 2.1-liter makes plenty of torque.” Does 10% wiggle room in power really matter? I don't think so. It's more the gearcase and prop, although I wouldn't be so sure that the HO/Pro XS/SHO variants with their distinct tunes are running exactly the same peak power as standard, assuming the standard engines aren't underrated to start with.
  3. Mine just died without explanation as well. 9 months old. Working fine the other week, went out yesterday and she's dead.
  4. I have a 2020 Yamaha 25hp on my estuary boat (Quintrex 390 Explorer Outback). The little Yam is a beast on that hull. Boat runs a full floor/casting deck, battery, electronics, fishing gear, esky, 2 people and dog. So probably not far off a 420 Rampage running light with 1 person. Heaps of grunt out of the hole and does mid 40s flat out. Perfect for the ~4m open hulls. If it were me w/ a 420 I'd still prefer max horsepower but I think the 25 yam would hold its own. Probably find the limits with 3 people and gear though. Streaker Marine fit the 25hp to 420 Bustas, maybe give them a call and ask how they go 3 up in that config.
  5. While not in the Shire, I'd take it to the Boat Pimpers in Condell Park if you want a top quality job.
  6. Heavier build is more about ride than strength. Probably not worth too much thought in the ~4m class, particularly if you're only working estuaries. Quintrex recently dropped the 2mm option on their 1.6mm Outback Explorers, only really adds weight and in the sub 4m models there's usually more benefit in being lighter- low hp 4 strokes, car toppers etc. Quintrex/Stacer/Savage come from the same factory as mentioned, although the bottom sheet pressings are usually different on the Quintrex models. If you want something that'll do well in bigger chop, starting point would be the 420 Renegade and equivalents. They weigh 2-3x the standard 4m open hulls, you will need twice the hp (50) to push them and twice the money to buy them.
  7. To date the best modern 150hp produced. Big displacement, torque curve like a 200hp, only 206kg.
  8. I'd be wary of shock absorber type pedestal designs, when they bottom out the force is actually amplified and can do serious harm. I run sharks personally, bit pricey but they're safe.
  9. They essentially took the Bar Crusher solution (which knowing BC was probably itself 'borrowed' from somewhere else) and improved it a little (spring loaded instead of a bungee). Mine works great. Helps that they design and build their own trailers, they fit to the hulls like a glove so it's pretty easy to nail the retrieve.
  10. Quintrex do not bring in hulls from China. Telwater was doing that for a little while with the Savage 'glass range, but their bread and butter alloy hull range (Quintrex, Stacer) are still all Australian. Whether BRP who now own Telwater will push for an imported product down the track is anybody's guess. In relation to stitch welding, the top decks are stitch welded and you pay more to have it fully welded, which is a good idea if you want the paint to have the best chance over the long term. Agree it would be nice if they were fully welded as standard for the price you pay, although granted with the higher price you're also typically getting better resale value than the lesser known brands and a larger dealership network. They're probably a bit like Toyotas - a little bit pricier than their lower cost Korean competitors but part of what you're paying for is that intangible quality of it being a Toyota and thus easy to sell down the track. The Renegades for example do very well in resale. Not sure you'd be as comfy selling an Anglapro or lesser known craft after a few years. Regarding Chinese builds, I believe Whittley has recently started importing Chinese alloy hulls. As long as they're keeping an eye on quality control, I'm sure they're a decent thing. The Chinese have well and truly demonstrated by now that they can produce very high quality items when they're not building purely to cost and there's some oversight. If it helps more people get into a newer brand name boat for less, it's not the worst thing in the world.
  11. I run a second battery and a jump starter. There's comfort in knowing you can leave electronics running at anchor without wondering how low the battery is getting. The mini jump starter lives in the cab as a last resort.
  12. Both good brands. The Bar Crusher has more a cult-like following, will probably hold its value better. One key difference is the Bar Crushers are quite narrow for their length. The Yellowfin will be a wider boat and probably longer too (BC tend to overstate length). But with the narrower beam, the BC will likely ride better, although won't be as stable at rest as the Yellowfin. Both good rigs from respected brands. For me I would go the Bar Crusher, they're built well and typically get a good wrap by their owners. Although I'd also be looking at Surtees, i.e. the original NZ Company that Bar Crusher copied (and continues to copy).
  13. In my experience we rarely get assists concerning newer engines of any make and when we do, it's generally unrelated to the engine itself (fuel/battery/kill switch, etc). All of the late model engines are very well sorted nowadays. Very rarely if ever do I see assists of ETEC powered vessels, which is not bad considering they're probably the most common late model engines on Sydney waterways, usually on Quinnies and Stacers which are rigged with them from factory. MRNSW use Suzuki outboards, but that's due to a supply deal with Suzuki, not necessarily because they're reliable. Water Police and Maritime around here run Mercurys (Verados) and Yamahas.
  14. Government funding does not cover the costs to run a Marine Rescue unit, not even close unfortunately. MRNSW rely on all 44 units to fundraise all year round, in addition to donations from vessel assists and local sponsors. Kudos to OP for donating, every dollar is needed. The costs to keep a unit running are astronomical. At Solander for instance, in the last 6 months they have incurred over $200k of expenses relating to repowering one of the vessels and replacing the dock at Hungry Point, which was more than 30 years old. Then consider the yearly fuel and maintenance costs for two 600hp Kevlacats and the ROIP radio operation, the government contribution covers maybe a little more than half of what it costs to keep the place running. You also have other expenses, for instance recently at Solander there was an ongoing problem with human garbage breaking into the Port Hacking vessel and stealing equipment which made the papers. A security fence and gate needed to be installed at the dock. Then when one of the vessels was off the water for maintenance, a centre console rigid inflatable was used as a backup, short lived unfortunately, as someone decided to trespass onto the grounds and snap the aerials off, cut the fuel lines and take a knife to the seats.
  15. Might be pot luck with that guy, we had some clears done by him and they were shocking beyond belief. Took them back and he didn't want to know about it, told us he's too busy to sort them out and to come back in "maybe a couple of months". Dirt bag. Ended up having them redone elsewhere, paid twice but lesson learned, some people just don't stand by their work.
