Default Repowering a deep vee Parker

Hello All!

I am new to forums, so bear with me please! I have been reading tons of forums both here and on classicparker, etc, and cannot seem to find the information I want. I started a small water taxi service based in Midcoast Maine recently and am looking to get a more solid reliable boat than I have been using. In comes the 2001 2530 with twin 2001 hpdi Yamahas I will soon be closing on. I am very excited to be joining the Parker community and am curious to hear your thoughts on the 2530, or the deep vee 2520.

The reason I have decided to post to the forum is this. I am looking to move the hpdi's to my 258 Mako and repower the Parker with a single engine. Right now there is an Armstrong bracket that can hold either one or two motors with a maximum of 500 hp. I like the simplicity of having a single outboard with a limp home kicker, but understand the benefits to twins as well. Seeing as I will be running upwards of 8 hours a day, I will be putting some serious hours on whatever I do get. Right now I am looking at the 300 Zukes and Evinrude G2s. What are your thoughts regarding switching to one motor? What is your preferred setup? Unfortunately cost is a limiting factor...

To give you a slight bit of background, I am 26 years old, I started this business with an 82 Mako with twin 1992 150 2 stroke Yamahas that I bought with lobstering money. Unfortunately I am not exactly cash rich, so I am looking to sell the Mako with the HPDIs for money to put towards the repower on the Parker. Any and all thoughts would be greatly appreciated! Thank you again everyone!

The boat I am closing on is the 2001 Parker on Yachtworld if anyone wants to take a look, I can't post a link until I have made 10 posts!

300 Suzuki. If tight maneuvering is essential twins would make life a whole lot easier for the captain.

Is this the boat? https://www.yachtworld.com/boats/200...Cabin-3250794/

How fast does the boat need to go? If not over 25 mph, I'd be looking at a boat with a diesel engine.

Oil changes on two ouboards twice a month will be expensive, but nothing compared to your fuel bill!

Here's some performance data on Parkers to give you a very rough estimate on fuel consumption:

I'm a big fan of a single engine setup, keeps things simple. I would opt for the Evinrude G2 300, fuel and maintenance savings will be significant at the hours your are looking to run. Also for a single engine on a heavy boat you want plenty of torque which this motor has.

Personally I think it's hard to beat the cost effectiveness of keeping your motors though. The HPDI's are as fuel efficient as any four stroke, plus you don't have to buy them! But if you're dead set on getting a new motor, G2 300 gets my vote.

Thanks for the links DaveHNL! That is indeed the boat. And seeing the stats for a new pair of Yamahas on the same hull (below waterline) is definitely helpful. Doesn't make me feel quite so bad burning 16 gph at a cruise of 24 to 25 kts. I have just heard mixed reviews about the hpdi and was hesitant as the parts for them are apparently really expensive.

There are actually a few lobster boats out where I live offering a taxi service, but no one that can cruise at over 16 kts, so having that extra speed has given me a big leg up in the competition. I have been searching for a fast diesel boat for a few months, but they are often way out of my price range if they even exist!

Hey Fatbill, I think our heads are in the same place. The more I think about it, the more sense it makes to wait. I would love to have a new G2 300, but buying the boat might be enough of a hit right now! The torque, less required maintenance, 10 yr warranty, fuel economy, etc sounds too good to be true!

Thanks for talking some sense into me! Hopefully I can put up some progress pictures once I actually get the boat home where it belongs!

Glad I could be of some help! People come on here all the time asking opinions about a repower. The only times I really think it makes sense is if your engine no longer meets emission requirements in a certain area or if your current engine is unreliable and very costly to repair.

The small block HPDI's are amongst the best motors Yamaha has ever made. Yes the advantages the G2 has over other motors is indeed real and very attractive, but can you justify the cost when you already have something that is now effectively free? Would you pay a huge sum of money to replace your current cars engine with a new one?

Of course, if you think your life would be considerably improved by owning the G2, then by all means go for it! Our purpose is to find happiness, and if that's how you do it, pull the trigger!

Honestly, this is great to hear. I got scared by my last purchase that had twin Yamaha 150s (Saltwater 2 series), which ended up with a bad cylinder that the local Yamaha dealers wouldn't fix or resleeve...

Any way, I'm going to keep the HPDIs for now and try and get everything I can out of them. Someone on another thread mentioned Permatrims which is something I hadn't even considered... any thoughts on those? Or perhaps any other ways to squeeze the most efficiency out of what I do have? The boat already has stern mounted trim tabs, and the motors are on an armstrong bracket.

Thanks again Fatbill!

Clean fuel and clean filters, Great engines but yours are now 17 yrs old.

Very true. I'm definitely going to ensure that the fuel going in is perfect. Probably going to replace all the fuel filters (internal and external, vst screen), additive in the gas, etc.

Any particular additive you guys like? It just had the tank filled a month ago, and I don't want to run bad gas, but it's hard to chuck 173 gallons of what could be perfectly fine fuel!

Read up on all the filters on the hpdi, there's a bunch of them, I use the mercury quicksilver fuel treatment which I find to be the equivalent of the Yamaha ringfree but more than 50% cheaper.

Will do pathfinder11. Thank you for the advice!

I use PRI-G with e-10. Never had an issue but fuel doesn't stay in the tank for more than a month

Hello, double check the fine print on the 10 year warranty, you might find it significantly reduced when used in commercial service, had a commercial boat with a 2 stroke, admittedly about 15 years ago, would have preferred the 4 stroke, hope this helps

Single Suzuki DF350 would be nice. I saw a Parker 2510 with a single DF350 being towed out of Maine a few weeks ago behind a silver Suburban. First DF350 that I had seen on an older boat.

Remember he said around 8 hours a day use possible . In less than 2 weeks that's an oil change on a 4 stroke.

Or a lot of burnt oil, pick your poison.

at that rate I would much rather add it. A lot less time consuming .

Yeah, that's how I feel for sure. Although I like a lot of aspects of the 4 strokes, the lower maintenance on the two strokes of the future sounds really nice. Especially at an easy 600 hours for the season (3 months).

Also, I got the boat today! Launching soon!

Commercial guys mostly do not do 100 hour oil changes. 2-300 hours or more is more like it. Still get 5k hours.
